Alright, here's my situation. I'm a high school student in a quite demanding enriched science program that basically requires you to have a laptop. Until a few weeks ago, I used an old Toshiba Satellite, but now it's having hardware troubles and will no longer boot properly. I need a new laptop, and fast. I want to switch to Mac though, and am tired of slow, buggy PCs. I'm thinking of either a basic MacBook or a MacBook Air, and would like some advice on which to buy. My main concerns are portability, since I must walk several kilometers to and from school as well as carrying it around the school, and long battery life, as I am using it almost constantly throughout the day. I am thinking of a MacBook Air 11 inch, but I'm worried about the slow specs and smaller screen, as some of my classes involve resource-jogging software like Photoshop. I also thought of a basic white MacBook, but I don't want to buy right before an upgrade, and also can't really afford to wait an indefinite amount of time. My parents, meanwhile, do not think I should buy a Mac at all, and want me to get a basic PC laptop or netbook. What do you think I should do?
