Wow. I didn't know that was possible! Ima haveta try it. You can easily see I'm obsessed. I'll add it now.

Seriously, a chip like this hasn't been out in a long time. Sure there are more powerful ones like the BeagleBoards and RPis, but they require more support hardware, space, components and power. Hell, the stm32f4 can run with just a few capacitors and no external crystal, and still have 24 analog inputs, two analog outputs and floating point. Plus it has internal cache so it can run at 168+ MHz and DMA, etc.
