Ok I have a dilema... I'm just about to start graduate school and I've been thinking about upgrading my 1 ghz 15" powerbook to a newer 1.5 ghz 12" model. My reasons for upgrading are as follows. 1. Improved battery life from the smaller powerbook. My 15" currently last about 1 1/2 hours with a full charge which means constantly worrying about the battery during lectures etc... 2. The newer Al PB's seem to be much studier than the older TiBooks and I'm sick of worrying about my 15" knocking against my books in my backpack. The screen is just too flimsy and the fact that the keys rub off on the screen is just plain annoying. 3. Smaller size equals less weight and less of a "space hog" on a desk. My questions are pretty simple. Is it worth it? Would you do it? Is there anything that the little PB can't do that mine can???? I know that we are expecting a PB update soon with the Intel chips but I've heard that the speed bump will be minimal. Is there any features I should think about holding out for that will be in the new PBs? Thanks for any help you can offer. MAC's RULE!
