    Hibernate to RAM is infinitely faster than having to copy all that data anywhere, and the power requirements of keeping RAM refreshed are ridiculously low. My desktop in suspend (S3) draws 1W more than fully powered off. Powers up in maybe 4 seconds (as fast as the HDD can spin-up, really).

    An SD slot would not only provide for a lot of capacity (way more than what you get on a CDROM), but also a means to stop writing, and a means to swap out bad flash or reload it in another computer.

    The cost of the hardware needed to support an SD card slot (fully, in hardware-only, before POST) would be more than the cost of a lot of ($40) low-end motherboards.

    Directly wiring a Flash chip to the memory space is MUCH cheaper, and what's more, the most basic socket for the Flash/CMOS has all the same advantages of an SD card slot... ie. It's not the inability to swap chips that stops people from doing more experimentation with their motherboard's firmware.

    You can't prove a negative, only a positive. The onus is on you to prove that there is at least one ARM system out there that is competitive with x86.

    Who the hell cares about it doing lots of nifty multimedia anyway? This thing is enabling people to have computers in third world countries. Fitness for purpose.

    Part of the "purpose" for the OLPC is to enable things like a software spectrum analyzer, VoIP, video, audio, and many other types of multimedia. Your only argument seems to be that you don't think the OLPC should be able to do the things that it does.

    If that was the design, even the lowest-end ARM chip would be vastly overkill, and it could instead easily be a $15 digital organizer, calculator and text reader. Of course it wouldn't be a "computer" by any stretch of the imagination.

    And if you're really fussed about playing back multimedia, there are plenty of ARM-based CPUs around that have hardware video and/or 3D accelerators in them.

    That's a complete non-sequitur, trying to excuse the ARM's poor performance by including other hardware to pick up the slack. As soon as you include hardware acceleration, the CPU is almost entirely out of the picture, only being used to move the bits across the bus. An 8080 could "decode" 1080 h.264 video with the help of a hardware accelerator.

    If you were to compare general/integer computation between even an old ARM9 and the Geode, an ARM9 will beat it clock-for-clock.

    By all means, point me to some benchmarks. Your claims fly in the face of every bit of embedded work I've ever done.

    In fact a couple years ago I figured that drastically underclocking a PIII to the point that it used ~200mA like many ARM chips would result in a chip that could easily outperform anything available out there. It's just not practical for embedded systems because of the price of a PIII, and the rather complex supporting hardware for such desktop CPUs, as compared with ($5) ARMs. Yes, even in the most power-frugal situations, price is an even more major concern.

    Floating point? We're not in the dark ages any more in the embedded community. For starters: WE DON'T NEED IT. Emulation suffices pretty damn well for every day usage. It's not like Excel requires 8GFLOPS to recalculate 1,000 cells. These machines aren't for games either (and hell, you can do games without an FPU anyway - we managed for decades perfectly well).

    Emulating floating point with integers is painfully slow. Of course Excel would be okay with an emulated FPU, but the kinds of multimedia being done on the OLPC are very float-intensive. Try playing a few videos on your ARM test systems and see just how fast of a CPU you need... Hint, it'll require a number of clock cycles, far in excess of a Geode.

    If you still really, really must waste a big bunch of silicon area to hardware floating point, then there's plenty of solutions out there for ARM which are 1-2 MACs per clock. That'll match the Geode easily. Oh, and also vector stuff should you want that.

    I haven't had the opportunity to work with ARMs having an FPU, but everything I've heard (second hand) says they are extremely basic, and very very slow.

    And finally, one of the OLPC developers publicly said that they investigated numerous architectures, and the speed of floating point calculations was precisely the reason they settled on x86 and the Geode.

    With IE being part of the operating system, and commercial software companies being required by law to provide free security updates, I imagine Microsoft was opening themselves up to all sorts of legal liability.

With WGA routinely denying legitimate users, and apparently no method provided for users to have problems with WGA resolved, this could really have forced Microsoft to continue relasing patches for IE6 for several more years.

    Micrsoft seems to be intentionally trying to avoid such legal problems for the rest of their security updates, by allowing automatic updates to be downloaded, even if WGA checks fail and you aren't even allowed to use the windowsupdate website directly.

    There is no reason that standard 2 hour movies can't be distributed on a double-layer DVD using a modern compression format -- which are supported in just about every $99 DVD player I see at Circuit City.

    Divx isn't a modern compression format anymore. h.264 and WMV are much better, and they are in-fact the codecs used by HD-DVD and BluRay... Yet they still need as much space as is available on the disc to make good-looking HD video. You literally CAN put HD on a dual-layer DVD, just as you CAN upscale your DVDs to HD resolution, but there's little point in it.
