I've saved quite a bit of money during the summer to buy a car in next April but I also have my eyes set on a laptop so I thought I could spend some of my car money for a laptop. This laptop would be mostly used for taking notes in class, doing homework while on the go and browsing the web. What I'd like is a good solid notebook that I won't mind travelling with and that has wireless internet, a CD-RW and a DVD would be a plus. Battery life is also important as I'll be using it in places where I can't plug it (bus, subway, some places at school). I never had any experience with Macs but some of my friends are really sold to them for laptops and I've been looking for the 12" powerbook and also the iBooks on their recommendation. Will I notice a big speed difference or in build quality between a Powerbook and an iBook and would a PC be better for my needs and budget?
