I know, it's not a Mac, but for $10 it's pretty cool. Pentium, 775MB HDD, 16MB RAM, CD ROM, Win95. Complete with original User's Guide, external floppy drive, 10/100 LAN PCMCIA, 56k MODEM PCMCIA & AC Adapter. I think the battery's dead, but what are you gonna do for $10!

I really wasn't into PC stuff until I my buddy gave me a ThinkPad T42. That's a very well built machine. I'd put it up there with (dare I say) my Pismo as a rock solid laptop.
