Another thing that I keep realizing about myself, then forgetting about, is my absolute interest in older systems. The NetLink, XBand, and Saturn projects drew me to this site. Programming for the 360, Wii, PSP, PC, and iPhone just don't appeal to me all that much.
A project like this, however...:

... I almost bought a ZX Spectrum off of eBay immediately after seeing this video. I'm still VERY tempted to. I did actually make a hard drive speaker once, and would love to do a project like this. I actually have a spare scanner, used to have a couple dot matrix printers... and I have some old Atari systems lying around... plenty of old hard drives, floppy drives... I've thought of making a microcontroller into a music system...
Darn. Too many other projects right now. But I am VERY tempted. Filed away in that pile of projects I'd love to do someday.

I have my Saturns, I have some of my games, I have a RasPi. Gotta put all this stuff together!
