I was wondering what you guys think on how much RAM Tiger is goign to need to run well. As soon as it comes preloaded, I'm goign to buy a 12-inch PowerBook with a 100 gig HD and 768 mb of RAM, and yes this is the most I can get since I'm 15 and this is a birthday present from my parents to replace my 1GHz, 512 RAM, 30 gig 12-inch iBook. Will this be enough for a smooth ride?
