They have an Arduino ADK on clearance at radioshack for $19.99, and I just what to know what's the major differences can it still do everything the Mega can do? I don't want to use it for android just electronic projects.
The ADK has a USB Host controller chip...
$20 is a great price.
Here is the schematic of the ADK board and standard mega board.
Between those two drawings you should be able to determine any conflicts in near or future projects.

ooooh. Radio Shack is clearing out some Arduino/etc stuff. I picked up a $20 ADK and a $5 motor shield.
(I just wish I believed that this wasn't a bad sign WRT them continuing to carry Arduino Stuff.)
