Hey folks, I'm def. buying an apple laptop but kinda unsure of which to get 12" or 15" powerbook. Basically I think the 12" is great for portability, and small size. 15" is great because of screensize and for further down the road, it's more upgradable. I don't know if the 15" will end up being cumbersome or if it'll be just fine. So yeah, kinda torn, and ideas? Suggestions? personal preferences, anecdotes, fireside stories?
