I guess I've got mind whip lash from the transition to Intel. It's still kinda hard to wrap the mind around these speed improvments. I'm still used to the very modest speed bumps from the PPC days.
How wonderfully refreshing it is to see these leaps in speed with each product update. I hope this pace keeps up. Some may disagree, but I think it's spectacular compared to what we used to get from Moto/Freescale/IBM.
Nonsense. Maybe at the very end, but we used to see updates like 800mhz-->1Ghz. That's a 25% increase in performance (if processor power is the limiting factor). Even the G5 went dual 2.0 --> dual 2.5 in one jump, which is a bigger increase than this.
This is NOT the promised 20% increase; it's a 10% increase. Some areas may show more, but that only means that some show less.
I'm just not sure why everyone is so impressed with these imacs. The 24" was a great addition (and the low-end 17" for $1k is nice too), but the 17" and 20" are the same as the old models except for a processor speed bump and 1 GB RAM standard. All that for less money is not bad, but it's hardly thrilling considering that it's the first update in 8 months.

This may have been asked and answered before, but is the common belief that USB and Firewire will be completely gone soon? For example, my Macbook Air has room for only two ports - a mini-display drive, and a USB drive. Is the idea that the Thunderbolt drive will replace the USB, and that purchasers of the new Air will use an adapter of some sort for "old" USB peripherals moving forward?
If Apple has this expectation, they had better at least sell an appropriate adapter/hub. I've long thought a thin, form-matching hub that connects to all of the ports on one side of an Apple portable would be a great idea. If Apple can make a 2- or even 3-port USB hub off of the Thunderbolt port (especially if a Mini Display-Port is also available) for ~$50, that would be golden for this type of MBA plan.

Regardless of the tool, however, it is usually much better to let the OS dynamically schedule threads across the cores. Unless the programmer has some reason to try to control this, the alternative is some resources (CPUs) being overcommitted, while other CPUs are idle.
It doesn't matter who has the better tools - it's usually better to let the OS decide microsecond by microsecond how best to schedule the CPUs, than to have the developer make those decisions at edit time.
I've used the SetProcessAffinityMask APIs fairly often, but it's always been for specific test or benchmark situations. I have a hard time thinking of a situation where a general application would want to statically control the scheduler - it's just "bad think" to even try. (Except for those weird-a$$ NUMA Opterons - you can be really scr3wed if you have to go through HyperTransport to get to memory. I check NUMA topology, and use affinity to keep the AMD architecture from killing me.)
I also agree it's not the best strategy to deal with CPU scheduling...my example is linked to the following page, I presume...perhaps core affinity scheduling is also there:

Hi, I've been lurking for the last few months waiting for the refresh. This'll be my first home Mac (got a Mac Pro and MBP in my office).
I ordered the 27" i7 Quad yesterday with 2GB 6970 and trackpad. Got the standard 4GB RAM and will add some more myself. It's a shame about the target display mode as I was hoping to use the iMac sporadically as a display in the lounge when my buddies bring their Xbox 360's round but hopefully there'll be a HDMI/DVI/Mini display port > ThunderBolt box. It's a pretty expensive occasional use proposition though and it might be easier to throw a �100 TFT display in a cupboard to get out for gaming.
I look forward to seeing some benchmarks.

O no! Our cell phone technology is behind that of Europe's, where the small, congested spaces make it easier to unveil new cell technologies! The horror...
Agreed. The U.S. is pretty much behind everyone else as far as cell phone technology goes. Do I care? No. My cell phone takes and gives calls. Who cares if it can take 30MP photos and watch steaming TV and movies and play Crysis at 120fps and pay my bills and rob convenient stores and solve world hunger? When I get a new cell phone and the salesman starts running off at the mouth at how cool it is and all the groovy things it does, I stop him and ask, "can I call people on it?" If the answer is yes, then I'm happy. :D

The MBPs could have DisplayPort 1.2 if it were not for the damned connector merge.
The mini-display port connector is part of the DisplayPort 1.2 standard and is seemingly seeing wide adoption from PC laptop and display makers.
The DisplayPort 1.2 specification requires support for DisplayPort 1.1a on mini-display ports, but I don't see anything that precludes it supporting 1.2 signalling.
Can you point to an article that details how Thunderbolt is a problem for this? The Thunderbolt controller, when connected to a DisplayPort 1.2 (only) display, could fall back to DisplayPort mode like it does now, could it not?
Intel should have stood their ground on Thunderbolt... Would have pushed component manufacturers to make more Thunderbolt devices, now we're going to have a mish mash, and those of us with Macs are getting the shaft because we won't get USB 3.0 from Apple...
I wish they had announced that IvyBridge was USB 2.0 only, but this delays USB 3.0 adoption by a year.
There's been strong support for Thunderbolt, so that year might be enough to kill USB 3.0, which hasn't exactly taken off.

You both think into it too much:
- FireWire was gone from Apple's "future of notebooks" since the beginning of time (2008:rolleyes:)
- Thunderbolt is not replacing USBs, it's a supplement to DisplayPort (and can connect to both display and peripherals simultaneously)
Thanks.

The USA is on borrowed time. Unless the US can drastically make changes, things are really going to get worse.. as if they aren't all ready. Already, the corporate run media reports everything is getting much better.. I don't believe this over a hill of beans.. Consider this:
Job market still sucks.. unemployment in the US is over 10 percent despite what the media says being 8.9 percent..
Economy isn't really growing much at all.. at best 2 percent growth which does not mean its getting better.
The trillions of debt this country is in.. I fear within the next few years the debt is going to get higher + rising gas and food prices.. and most Americans are too stupid and blind to the corporate media saying things are ok.. I should know. I am struggling with gas and almost had a fight with someone at a gas station because I called for a REVOLT against the corporations controlling out lives(gas companies and the middle east OPEC).
3rdly, cost of living is rising, and food... So, is the US getting better? Hardly.. and no one seems to care or want to do something to change it.. The solution proposed by Congressman Ron Paul..
Complete ABOLIITION of the Federal Reserve and a repeal of the 1917-1919 federal reserve signed by Woodrow Wilson.. and also an end to the IRS and its tyrannical strangle hold on the citizenry..
The American people should take ownership of corporations and not allow corporations and banks to rule over the people.
Only then will America be able to recover from all of its ills.. and if someone can't recommend Ron Paul for 2012 presidency, then we have signed this country's death warrant.
And yes, the recession is not over.. in fact, we might even be heading into economic depression very shortly.
Its not about capitalism here.. its about ENDING CORPORATE RULE and BANKS ruling over us all.
Its time for Americans to take back the country from corporate elites and banks. DOWN WITH THE FEDERAL RESERVE!!! Power to the PEOPLE!

There is absolutely no advantage whatsoever in having USB survive past 2.0 at this point. With 3.0 barely entering the market, there is no value in letting it get a foothold. It is pathetically obsolete compared to TB.
What is with the comments about wanting USB 3.0 on Macs? What a huge waste of time and money - you should be wanting TB on more peripherals. Even if Intel is going to be dumb enough to keep USB 3.0 around, hopefully Apple will hold the line and refuse to put it in Macs. With Apple's resurgent strength in the computer market while everyone else is tanking, that would be enough incentive to get the peripheral makers to adopt TB.
What are you talking about? Practically all SB motherboards for PC's support USB 3.0. I'm enjoying USB 3.0 speeds on my new PC, plus the ports are backwards compatible with USB 2.0.
Don't get me wrong, I can see what TB offers & I like what I see, but USB 3.0 is here to stay. Intel's support just emphasises how important a standard USB 3.0 is.

You'll go nutz in couple decades when our CPU's aren't even in our homes anymore. Start to get used to the idea of "cloud" slowly :)
not going to happen
the entire history of computing is giving more power to more people. the cloud has always been there, even with the first PC's. but the trend is to give more features to less powerful devices

Only in America.... Bad form unless it was in defence. How about non lethal take downs, fair courts and appropriate justice, such as jail with community service, get criminals doing something constructive for society and trying to get them back on track?
The right to carry guns and to kill absolutely baffles me. Surely shooting and killing is a worser crime than stealing? The threat of being shot/killed sounds too authoritarian/totalitarian for me.
I can't believe the mentality of people on these forums sometimes! Each to their own I guess... Democracy and all...
Yes, it makes perfect sense to use some form of non-lethal force when somebody is shooting at you with intent to kill. Did you read the article? The guard was fired upon.

Then you pay 9.99 for the rights to what ever movie and it is streamed Slingbox style to your Airport Extreme that has HDMI, Component, Composite etc outlets for your TV. Then you have your movie you bought anytime all the time but never have to take storage of your own, and never have to deal with downloading or anything.

Disagree because "Ope System" is not the accepted abbreviation: "OS" is. Do you think Microsoft should be able to rename Windows OS and then trademark OS? Of course not, and accordingly Apple shouldn't get a trademark on App Store.
Apple should lose this dispute on the merits. Whether they do or not will depend on the caliber of their lawyers. On the two briefs we've seen so far, Apple clearly has some advantage, so they might pull this out nonetheless.
Apple has always had apps, Windows has programs and never had apps. MS NEVER called them apps or applications. Until now. They have no basis for this claim, the word "app" is as foreign to the windows world as a cron job.
