I've always owned PCs. I'm thinking about getting a MacBook, especially if I go back to school next fall. Excuse my ignorance on computers, but will I be able to transfer stuff from my PC to my MacBook? (pictures, music, stuff like that) Also, how hard does Apple hit your wallet? Besides the computer cost, tax, and a warranty/care plan or whatever, and a case for my laptop, what else would I reasonably be expected to buy? (I haven't purchased a computer of any kind in over 5 years so I don't remember much)
