I've been looking for a notebook computer to act as my only computer in college for several months now and had narrowed my choices down to 2 PC laptops before I began to consider the powerbook. It really looks like a great, well-built machine, and I'm eager to see the advantages of OS X. My problem, however, is that I'm not sure I can justify paying $2500 (including education discount) for a machine I'll probably use mostly for the internet and school papers/projects. Does the powerbook offer enough to me to make it worth spending $500 more than I would on a comparable PC laptop? Thanks!
