OK, it's really old, but it's got a 366mhz G3 processor, 320mb ram and a 10 gig hard drive and it makes an excellent (portable) jukebox! It's an Apple clamshell iBook in Indigo!
Built to stand up to the rigours of life on the road, it's already DJ'd one party in its short time with us, I think an airport card is on the books for it next. A new battery wouldn't go astray either...
