My 12" powerbook is coming in any day now, and being relatively new to the mac scene, I was wondering about must-haves. I'm an undergrad, and probably majoring in English and/or political and social thought but i'm managing web sites for a few professors as a side job... lots of typing, lots of moving, etc. Should i get officemac or just use open office? Anything else to make my new baby feel at home? Thanks!
