I intend to buy a new powerbook soon, but I`m unsure what model to go for. It`s either the 12" or 15" Powerbook. My main concern is how am I going to feel carrying the 15" Powerbook around? I don`t really want a monster that takes up a alot of place and feels dangerous to just put in your sack. I currenty have an 12" G3 600 iBook that feels very nice to just tuck away and pull up. It doesn`t feel super-expensive and fragile as an 15" might be. I looked at an 17" Powerbook at an neighbours, and while it certainly was nice and relatively light-weight, was quite too big for me. I`m going to use it "mainly" for university purposes, making notes and stuff in class. Though honestly it will more truthfully mainly be used for gaming, music and video. Of course the bigger the better for the later, and the 15" has a better graphics card then the 12", in addition to a faster processor, bigger HD and S-Video out (which sounds very nice). So is the extra 3" that much more of an ballast, or will I feel pretty much the same as I do know with my 12" iBook, ie not that much of a difference in terms of portability? I´m leaning in favour of the 15" since it has better specs, but what do any of you think?
