So what happens to all that e-waste when you throw out an old computer board because you don't feel like wiping it?

Well with this system on memory footprint, if my application doesn't need Ethernet I won't add one to the board, and if I don't add one to the board then the jack and chip won't be wasted or e-wasted.

You're making project-specific one-off PCBs, and you think this is less wasteful/more efficient than "wasting" an ethernet transceiver?

Can other computer-on-modules in a SODIMM package be used in the Compute Module IO Board they are developing? I've searched online, and I think the boards that the SODIMM modules are plugged-in to are called "base-boards" or "carrier-boards". In general, are these kinds of boards generic in nature, so that you can mix-and-match modules with different carrier-boards, as long as they all use the SODIMM package?

No, usually each manufacturer has a custom pinout for the SODIMM connector, they are not interchangeable.

For that you may want to look at the Qseven standard: http://www.qseven-standard.org/

This also gives you a bump in processing power as well, with the ability to use ARM or x86 processors. (of course it is a lot more expensive...)

How do they rate against Videocore IV? AFAIK, ARM core represents only about 2-5% of total computing power in RPi. And can you provide some links, please?

"Total computing power" is massively load-dependent. And I don't think The VideoCore IV is massively outstanding in the field of embedded GPUs. Links? This is turning into a let-me-google-that-for-you, but they appear very regularly on http://linuxgizmos.com

I see it more like a SIMD processor than a GPU. It's not massively outstanding, but there's a lot of value of it having an open documentation, a known instruction set.

There are really great cheap SOC's out there, in ARM land, to play with. Just look at these guys: http://www.acmesystems.it/aria Look, the rPi started off as a play-thing for kids, and there is now a valid rPi generation. It is expanding as a platform. But: in the industrial world, the rPi is a small fish. You can get an rPi precisely because some other industry has already driven the demand/price/costs down for it t…

There are, but they aren't close in specs and price to this one. The AT91 series are completely different in terms of functionality vs the Broadcom. The AT91SAM9 series don't even have a floating point unit last time I checked. This chip can do full 1080p h264 encoding/decoding/and support that resolution for display output (HDMI and DSI). This also has flash storage and 2x more ram onboard. This might be a close equ…
