This thing is major orders of awesome and is made entirely of win after it's been hacked. Shell prompt? Check. SSH/SFTP? Check. NES Emulator? Check. ScummVM? Check. E-book reader? Check. IM client? Check.
I also didn't realize how easy it is to completely reverse the hacks and return the thing back to out-of-box state. I can roll this thing back to Factory 1.1.1 or 1.1.2 whenever I feel like it. So when the time comes that apple does release the SDK, I haven't locked myself out of that route.
