My friend just bought a Macbook, and was thinking of buying his tired old tibook 400 (1 gig ram). The battery is very old and the screen is washed out, but I want something cheap that I can throw in my bag for the sole purpose of Pro Tools demos with my Mbox. How much do you think I should offer? Looks like ebay is all over the place now that the macbook/macbook pros are unleashed. Disclaimers: 1) I tried to post this in marketplace, it wouldnt let me?! 2) Before people start bitching about what a real pro tools rig really needs - I just need this for 4-8 track demos on PT LE. I've run it on an ibook 300 just fine. Thanks!
