The raw chip really isn't targeted to to hobby segment. But the time you
get done sticking on a PCB and surrounding it with the necessary
peripherals, you're way above the budget of any of these boards.

My one caution for everyone is not to get caught up in famous name of the
PI. There are tons of other contenders out there. Last month I purchased
two pcduino3 nanos:

Quick rundown:

- 1Ghz AllWinner A20
- 1GB RAM
- 4GB bootable NAND flash flashed with Ubuntu
- GB Ethernet
- SATA port. Not bootable, but can host root filesystem.
- 3V Arduino shield interfaces and IDE
-  multi-format 1080p 60fps video decoder and 1080p 30fps H.264 and MPEG4
   video encoder with its built-in hardware video processing engine.
- USB OTG in addition to 2 full sized USB2 ports
- Has the ability to run Android 4.4

$39.00 + $6.40 shipping.

Right now I'm trying to nail down how to boot a kernel from NAND flash and
pick up the rest of the filesystem from SATA. 

So take a look around as there are a ton of these type of SBCs floating
around:
