Hi, My 12 in 1ghz PB with 768mb ram is going to be retired after this xmas. I'm looking to upgrade to either a 2.4ghz unibody MBP or a 24in 2.8ghz iMac. My powerbook can still be used to do basic tasks (internet, civilization 3, Word), but I'd like to be able to run newer games (Colonization, Age of Empires, etc) and do some occasional Final Cut editing. Budget is about $1800. Please help. Thanks!
