Creative's stock up 30% in after-hours trading. The $100 million is a drop in the bucket for Apple, but it will certainly help Creative...

Looks like the iPods are still at 5G with some tweaks, which is weird considering they had a whole year. .
That is the common sense reaction. You're seeing mac zealots here trying to trumpet how great these new iPods are.
Updating a 4:3 screen with another 4:3 screen and claiming it's improved is like Yugo rereleasing their car and claiming it's improved because the gas cap is a different color. It's still a Yugo.

Is 20% speed improvement a lot for a core 2 designation?
The designation "Core 2" comes from the fact that it's a whole new architecture in the chip. The original "Core" processors aren't based on the Core architecture, they were based on the Pentium M. The Core 2 processors (Merom, Conroe and Woodcrest) are based on a 65nm dual-core 64 bit architecture - the desktop and workstation chips are based around the mobile Merom architecture.
Core 2 promised about 20% more performance at the same power requirement as the Core chip at the same clockspeed.

Will we see 1080p target display support ... It would be really cool to play xbox 360 on iMac in 1080p ... 720p ain't too bad but with all it's 27inch awesomeness 1080p isn't too much to ask for eh?

I bought a movie (Good Will Hunting) to try out the whole shabang and see the quality for myself. The 1.5Gb download took 6+ hours on my crappy adelphia cable modem (it feels slower every day, what am I paying 50 bucks a month for again?). I was satisfied with the image quality on my 20" Dell widescreen, but sitting at my desk to watch a movie instead of my couch isn't the movie experience I'm going for. Sadly, I probably won't be buying another iTunes movie.
Not that anyone cares.
Your right, we might not care... But, get an iPod, then hook the iPod to the
TV using the dock with S-Video connection. Looks awesome, and most cannot
tell the difference between it and a DVD.

Please explain - I have no idea what "that" is....

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've owned SMP machines in the past and often found it more useful to force CPU affinity of CPU-heavy tasks to a single processor, as Windows 2000 (which was current at the time) by default had a habit of swapping it between chips, resulting in a lot of cache-dirtying. I think it was the load balancing code, but it's been a while now and I don't have those machines handy currently. However, you could see some significant improvement in processing time on some non-parallelizable cpu-bound tasks.
I've no idea if MacOS does this, but at least in the case of Core 2 it shouldn't matter anywhere near as much, as the L2 is fully shared.

Maybe nokia does have a good stand in those countries but when it comes to smart phones they're already loosIng so is MSFT I don't c what changes I live in the states and am brazilean me and my uncle take about 10 iPhones a year to brazil sell them for 1200 US dollars we can barely make the airport one time I sold one on the plane!!! Ppl who buy smart phones have money and at least in brazil they're either getting a iPhone or a feature phone(prob nokia).... No one in my town even knows about winPhone 7 believe me I've tried to sell those.... Not much interest for android either....

Do no buckle to these power hungry tyrants Samsung. The stinger you fight, the more I will buy your products in the future.
LOL! Why do you have a problem with companies trying to protect their intellectual property?
At least Apple didn't wait years to file suit and if you remember, they did file many patents on the iPhone when it was introduced. They have every right to protect their IP.
But I know... this goes against your anti-Apple ranting.

What about a hotshot stock trader making a killing working 80+ hours a week on salary. Should we be allowed to work this much without overtime?
Probably not. If the bankers had worked sensible hours they'd have been better integrated with society as a whole which would almost certainly have made the financial crisis less likely.

What I'm hoping for is that Apple uses the metallic finish of its nanos. My Sony Ericsson has a metallic blue finish but is actually made of plastic. It would be sweet to have a real metal phone. I predict Apple will launch in a single metallic color (the nano black or silver), and then within a year or less provide all the nano colors.A partially metal housing is certainly possible, but if a phone has an internal antenna there has to be a plastic "window" in the housing that the antenna can operate through.
Metal housings are a pain for cell phone RF engineers because they have a nasty tendency to interfere with the radiativity (the "shape" of the radio emissions of the antenna). You generally can't use the housing itself as an antenna because it's difficult to get a uniform impedance match due to all the different ways people hold a phone, variations in skin conduction (not to mention SAR issues...), resting surfaces like metal tabletops, etc. The metal usually can't be left "floating," i.e., electrically isolated from the rest of the phone--though there are exceptions--and usually needs to be connected to the common phone ground to give it fixed RF characteristics, resulting in things like the spring fingers you sometimes see inside a phone that touch off on a point of a metal battery door.
The RAZR is an excellent example of this. The bulk of the phone housing is metal, but there are numerous internal grounding contacts for the housing, and the area around the antennas is plastic (the "chin" below the keyboard).

I just assumed that being 64-bit or 32-bit was a system wide principle, either or.
A 64-bit operating system is one that provides 64-bit virtual addresses to its processes. It requires a CPU that supports 64-bit virtual addressing. The C2D is such a CPU, and runs 64-bit code and O/S.
These humongous 64-bit virtual addresses need to be translated to a physical address to reach the actual memory. The 64-bit CPU has a list of pages of physical memory, and tables to map a program's virtual address to a physical page. Once that mapping is done, the 64-bit virtual address can be used as a "synonym" for the actual physical address. The mapping is per process - two processes can use the same virtual address without interference - the same virtual address refers to different physical pages depending on the process which is using it.
In the case of the Napa(32) chipset, the chipset only has 32 address lines, and cannot physically handle more than 4 GiB of RAM. Some of those addresses are reserved for I/O purposes (such as the 256 MiB that is mapped to the VRAM of the video card).
If you plug 4 GiB of RAM into a Napa(32) system, you'll "lose" the memory that is over-mapped by I/O space. For example, right now I'm typing from a dual-Xeon (32-bit Netburst) with 4 GiB of RAM installed. Windows reports that I have 3520 MiB of memory. I've "lost" a half GiB due to these I/O space mappings. (My 4 GiB Yonah laptop reports 3.1 GiB available - PCIe systems seem to reserve a lot more memory for I/O than PCI-X systems.)
Apple is apparently saying that 3 GiB is the limit, so that they don't have to explain PCIe I/O bus mapping to people calling to complain that OSX isn't using all 4 GiB.

Bye bye built in Superdrive. I'll look back fondly at the five times I used you in the past three years.
You know, I was against the whole "get rid of the optical drive" bandwagon back in '09 when I got my MBP....but in the couple years I've had mine, I've used the thing ONCE.
And if anyone asks, it was for printer drivers (which I probably could have gotten online but I had the disc readily accessible.)
I'm going to soon get rid of mine and throw in a SSD!

... and yet there is a conspicuous lack of a self-congratulatory press release from Amazon about their sales numbers. I suspect that despite Unbox starting with 2000 movies, they've sold less than 125,000 movies.
If that's true, I wonder if it's because folks didn't want to have to learn new software to make Amazon's solution work, vs. "just clicking" in iTunes?
