They're not just hungry for power - notice the driver support: VxWorks, 
WindowsCE, Linux, etc.  They're all full operating systems.  There's a 
reason they don't offer code for 8 or 12 bit microcontrollers - it 
won't fit.

On the other had, for $99 you can get a full linux computer:

About $200 or so will get you a computer with enough peripherals and 
attachment points to be useful.  They need to work on their physical 
mounting provisions (currently, there aren't any), but it's got 
potential.  Get one with a sound interface and you can theoretically do 
linux soundmodem packet with it.
