so i know this has been discussed and discussed, but i'm getting a notebook and had been leaning towards the powerbook.. but the fact that i'm living in a house with 8 guys for the next 3 years and would like some extra battery life along with durability i'm now thinking BTO ibook.. the lab in my graphics building are all emacs.. how would a 12" ibook compare to them? i know the resolution would be lower but i can deal with that.. there aren't enough emacs so we have to wait a lot, which is why i'm getting one.. so i'm not looking for huge performance, the emacs i've been using are plenty of power.. i'll be using quark, photoshop and illustator and dabbling perhaps in imovie.. but thats it.. ibook should handle this and riding in my backpack on the bike ride to campus everyday?
