Haha. Silver. Collector's edition?
Athlete's edition, I reckon, given a piece of silver weighs around 4 times more than a piece of aluminum of the same volume.

What is your firearms experience? How many times have you been shot at? Do you think the security guard make a Hollywood head shot?
I'm amazed that so many people are basing their judgment of the "head shot" on 3rd person shooter games and CSI. In the real world, anyone with training will always be aiming for the center of mass, and where he actually hits depends more on luck than anything else.
In other words, just because the criminal was hit in the head, doesn't mean that the security guard was aiming for his head. A mall security guard with a pistol shooting at a moving target during a gunfight doesn't have the accuracy of a Marine sniper shooting a sniper rifle at a stationary target.

What if you downloaded the movie to your Macbook Pro and went on a business trip? Or you only own a laptop?
HOW are the members of your family going to watch the movie?
Just copy it to the computer at home. How are the members of your family going to use a computer if you take the only one with you?

My iMacs have 2 Firewire ports (a 27" and a 24") which I use for TM and a SD clone external. The new iMacs only have one FW port - with 4 USB connections. Seems like a slower way to have to back up, and I see no externals out there that run Thunderbolt.
Am I missing something? :confused:

I agree with the guy who wants any iOS device to be the receiver of AirTunes music.
I hear all the comments about Home Sharing and Airfoil, but both are only partial solutions that work in specific cases. I, personally, nt my old iPod Touch to function as a battery powered airport express - with some battery powered speakers attached, I can stream music anywhere (including the garden, etc) at the same time - perfect for parties. I could do that with AirFoil, but that means when I want to stream from my iPad to my Apple TV or Airport Express speakers in the living room I need a different solution. Plus i'm not sure the Apple Remote app will allow me to switch AirFoil sources on and off, which means I have to go back to my Mac to change them, it's not properly integrated, so not a great solution. Acceptable, sure, but far from ideal.
With home sharing, your old iPod Touch already does this. It's just that you get to 'pull' the music from your library to your Touch, rather than pushing it from the computer to the Touch. Really, what more do you want?
In reality, this is a much better solution than acting as an Airport Express, which only allows you to play one music stream to any or all devices. With home sharing, different devices can listen to different music at the same time.

I'd bet it all that the iMac gets an Allendale with maybe a Conroe top-end option.
That makes sense, it offers some product differentiation, and saves Apple a few pennies allowing them to offer a lower priced consumer desktop. Mac Pros will likely get at least one Woodcrest dualie model on the top end and perhaps a Conroe on the bottom but it is entirely possible that it will be Woodcrest across the board, to achieve economies of scale both in purchase power and motherboard engineering.
I'd actually say they'd be more likely to go straight Conroe, TDP is the same, has speedstep so it throttles back, and the Conroe has a bigger L2 Cache- just like the Meroms that would be most likely for the iMac.
Could someone answer me this, who actually understands the Core Microarchitecture. Is the Conroe extreme edition (2.93 GHz) a better high end gaming chip than a quad woodcrest setup, say at 2.66 GHz? I've heard more than a couple comments that the Conroe is better suited for gamers than a Woodcrest but this makes no sense to me. Again please, no fanboy speculators answering this, I'd really like to know the rationale using some expert technological analysis. What makes the conroe EE so expensive? At a higher cost than the 3.0 GHz Woodcrest, it must excel in some regard.
Well, the main thing here is its a desktop chip not a server/workstation chip. Woodcrest is the same microarchitecture and all that. Just a 1333 FSB and slightly different clocks. The woodcrest's additional costs however would be a totally different MB/Chipset, and FB-DIMM RAM.
I suppose it may depend on how the game is written to take advantage of the cores.

To be fair, direzz is just one person, not a major corporation who pride themselves on providing peerless products with few defects. That being said, with technology, there's always a certain percentage of failure rate with new systems. Eventually they work those out, but if you're an early adopter, then you run a higher risk of being in that percentile.
Additionally direzz, you said everytime you've bought a new apple product it's had defects. Yet you still buy from them. There's got to be a point where you should just say, "screw it. I'm not buying from X corporation anymore because I get bad products every time." Vote with your money. Go buy somewhere else. I would certainly go to another manufacturer if every product I bought from a particular company was defective.
Then again, you haven't really told us what you consider defective is. Sometimes programs crash, even on a mac. Sometimes little things happen that make you say, "darnit." Then you move on because it's not that big of a deal. Then there are some things, like a MB randomly shutting down, or batteries bursting into flames that make you say, "holy crap! This thing is messed up! And this is my third mac that this has happened to!" In other words, don't sweat the little stuff. :)
To be fair to direzz, he said that every mac LAPTOP he bought has sucked, not every computer.
I will buy a macbook soon, but I am worried after so many bad reports. And to add to that a friend bought a 17" MBP not so long ago and the workmanship really did look pretty shoddy and rushed. Sure enough, the keypad is now white and there is a nice discolored patch on her desk where the thing overheated.. how apple compares to other corporations, I don't honestly know. I like apple computers because they have been the most stable machines I've worked with and owned...maybe I had the bad luck of the draw with PC's. Anyway, any company will make a buck in whatever way possible-and will even vilify itself when it gets caught going a little too far in reducing labor costs:rolleyes: . They do it because they know they can get away with it. My friend with the pos MBP doesn't even want to complain about it. I don't think she is atypical...
Neh, Merom, schmerom. Not sure why a small change in processor will suddenly make macs comparatively worse computers..Apple 'competed' with the G4 chip all these years, I can't imagine that failure to announce an update the same day as a bunch of companies that also make sub-par products is really going to make a big difference. I think the financial argument is just another way of saying:"I want a [insert computer name] with a Merom chip NOW."

Hilarious to all those people who jumped on the THUNDERBOLT bandwagon. No thunderbolt devices yet and they have the hideous old case design.
:rolleyes:
Like that Alienware you've been eying has a prettier design. Where are you going to find a better design?
Great, I've been hungering for a new Macbook Pro for quite some time, and was hoping I could hold out long enough to get a non-ugly model :)
I can't stand the UB look.
Again, I challenge you to find a better looking, better designed laptop chassis on the market.
Thinner, no optical...perhaps SSD only?
I'd prefer a smaller bezel the same color as the MBA. Say, 1/4" or a little smaller? Larger trackpad for more gestures?
It's called the MacBook Air. Go buy one now. Meanwhile us MacBook Pro customers will be happy actually having features.
There is your answer, people think it should be thinner
It's true. And they are the rare few that want only a MacBook Air with a larger screen and a discrete GPU. Good thing those people are in the minority.
Nice. My 17 MBP (Early 2009) will be getting close to the end of its life cycle by then, allowing me to easily slide into a new MBP.
End of its life-cycle? Is there an app you can't run on that thing? Or are you one of those people on here that can't be out of date? An Early 2009 17" MacBook Pro wasn't something to shake a stick at last I checked. Through true, it is older than a week.
Wow, you people...

Let me clarify, i made my decision before this news was posted here. I really dont see nothing wrong with waiting on this refresh especially if it will be a huge step forward(which i believe it will be).
The "step forward" of which you speak, of which is the basis of this article, is only in regards to the exterior design, nothing else. Sure if they improve upon the durability and the ease of servicing, that'll be a decent step forward, otherwise, we're talking about cosmetics, and again while most of the people who lurk these forums care about form over function, function is all that matters and it won't be that different next rev, redesign or not.
They already have that product...it's called the MacBook Air.
This.
Translated: Next macbook pro will be a macbook air. MBA will cease to exist as a discrete product line. Happening late fall 2011 (if we're lucky).
You have a very bass-ackwards definition of luck.
I think it's almost a given that they'll do away with the superdrive. There's no need for it. And if they move to flash storage, they could make it a bit thinner and lighter. It would be like a Macbook air, but with powerful mobile processors.
Right, because I get high-speed internet everywhere! Because my MacBook Pro has 4G (and because 4G, itself, is ubiquitous). Because with a "MacBook Pro", I enjoy the inconvenience of having to have an external optical drive (because after all, the MacBook PRO line is all about conservation of space). Most people with the anti-superdrive arguments don't realize how very selfish and ridiculous their stances are. Luckily for them, there's an app for that, namely the MacBook Air.
This, if it and Ivy Bridge, lower SSD prices/larger capacities come to fruition solidify my decision to stay with my 2010 and wait for the 2012 refresh.
Your computer is only one year old; at that point it'll only be two, maybe two and a half years old. Will you REALLY NEED a new computer at that point?
please get rid of the bezel. make it as small as possible.
please do not make it thinner. rather reduce footprint and keep battery life up.
Laptop design doesn't work that way. They won't make it thicker and if they reduced the footprint, they'd reduce the size (and therefore capacity) of the battery. Nice idea though.
SSD + HD - Optical Drive = Sold
SSD + HD - Optical Drive =! MacBook Pro
Sorry.
Or just get a USB optical drive and have the best of both worlds ... you won't be forced to lug around something you only use once in a while :)
If the ODD is integrated, I'm not forced to lug around an extra part when I need to use it. Or is your definition of inconvenience backwards?
Ehrrrm, a superdrive is what invariably fails first and gives your laptop almost an extra kilogram of weight you need to carry around. Because taking it off means losing warranty.
A superdrive is not a trait of a "Pro" laptop. The speed and reliability are. Imagine a RAID array of SSDs packed together in a package the size of a superdrive. Imagine a pico projector in that slot � this is what Toshiba is going to do real soon now.
A Kilogram? Have you ever held a bare slot-load drive before? They're barely suitable for paperweights. I'll grant you that the slot-load models Apple uses are disgustingly failure proned, but the solution is to design a better one, not throw the bloody baby out with the bath water. A Pro laptop is like a swiss-army knife, equipped with any tool ANY professional could possibly need. Hence why the "MacBook Pro" of any Apple laptop should have the optical drive. Again, if you absolutely can't have one, the MacBook Air is a decent alternative.
The optical drive doesn't make it "Pro" it makes it "outdated" and "unnecessary." If you need an optical drive by an external one, there is no need to hold up the majority that never use them.
Contrastingly, if you need to not have one, you can always buy a MacBook Air. I don't use my FireWire 800 port often, but when I do, I'm thankful it's there. The same goes for the optical drive. Again, if you don't want it, Apple makes the MacBook Air which comes without it for the truly space-concious.

Eh....While I make a terrible liberal because I believe gun control isn't a big issue, there IS such a thing as a lost cause, and that people usually get what they deserve.... I also make a terrible conservative in that I don't think a mall cop should be carrying a ****ing firearm, nor should he be going for a killing shot- shoulder/leg at MOST. And anyway, from the sound of it, they weren't even in the store yet- they were still in the process of breaking in. REAL police are hesitant to fire upon a fleeing suspect, why the **** is a mall cop shooting people in the head who are running away without any stolen property? Answer: Because he's not a real police officer and he shouldn't be carrying a ****ing firearm. Sounds like this will be hitting the courtrooms.
*Edit*
They've updated the post since I posted that...The suspects were armed and firing, so I retract the bit about shooting a fleeing suspect. I'm still not comfortable with a mall cop carrying lethal force....there are plenty of less-than-lethal options out there.

No, not at all.
An affinity mask sets the set of CPUs that can be scheduled. A job won't be run on another CPU, even if the assigned CPUs are at 100% and other idle CPUs are available.
And that, by the way, is why setting affinity is usually a bad idea. Let the system dynamically schedule across all available resources -- or you might have some CPUs very busy, and others idle.
Win2k3 also has "soft" affinity masks, which define a preferred set of CPUs. If all of the preferred CPUs are busy, and other CPUs are idle, then soft affinity allows the system to run the jobs on the idle CPUs - even though the idle CPUs aren't in the preferred affinity mask.
Another aspect of quad core systems like MacPro or future Kentfields: On these systems, two cores share one 4 MB cache. If an application runs on two threads, it can run on two cores on the same chip, or on two cores on different chips. Threads that run on the same chip can exchange data very quickly, because anything that is in one threads L2 cache is automatically in the other threads L2 cache, but both threads together have only 4 MB cache. Threads running on different chips cannot exchange data quickly; data that is exchanged needs to be transferred through main memory. However, _each_ chip has 4 MB cache, or 8 MB total.
In other words, some applications will run faster if using threads on the same chip, some will run faster if using threads on separate chip. It is quite hard for the OS to guess, but the application developer should have some idea.

I'm going to risk the ire of the maddening crowd once more, but I think somebody needs to come to Apple's defense this time. I love a good mob scene as much as the next guy, and I keep my pitchfork nice and sharp just in case the need should arise. But… the picture that Rogue Amoeba has painted in their farewell post doesn't look quite so black and white to me. Certainly, Apple could have handled many things about the situation better, but so could have Rogue Amoeba.
I definitely can see both sides of the argument. And I speak from personal experience. One of my company's apps, CraigsHarvest, was rejected for a similar reason: we had included a cropped version of the Setting app icon in our help file, in order to better direct our users to where to changes their settings. But Apple rejected it because we were using their icon. So, we complied and removed its usage.
But there has to be some kinda happy, middle-ground here. There already are a number of Apple-owned icons that we are allowed (in fact, encouraged) to use, such as Compose, Action, Bookmark (see below attached images). Maybe Apple could expand the range of images, icons, etc. they own that we, as developers, could be allowed to use.
