I've just bought a base level 13 inch Pro for my son for his birthday and he's delighted with it. I'm an experienced Mac user but mainly on desktop pre-Intel models (still using a G5 and a Cube...) A few questions: Battery - we've charged it up fully but is it best to cycle the battery down and up a few times at the start rather than leave it on mains charge? RAM - is there a spare slot or do I have to take out the existing 2GB to upgrade? Windows - yes I caught him trying to port some of his freebie apps from his old Asus laptop and explained they wouldn't work and to look on the net for Mac apps such as a guitar tab program. But assuming he'll want a few Windows apps what's the most cost effective way to run them if need be? Older Mac software - I haven't looked but do the current Macs comes with a PPC emulator as I have a copy of Office 2004 I can give him. Also, will this still be supported under Snow Leopard? Thanks!
