I am very happy with my Mac. I have a Powerbook G4 that I bought 3 or 4 years ago (ancient in computer years). About six months ago, I dropped it at such a horrendous angle that it got pretty banged up and dented. Amazingly, it still works. I had a small software problem recently that was probably unrelated and was easily fixed. Other than that, no complaints.
Are you in college or a college graduate? If the former, you can get good deals through your school. If the latter, your school might have special computer deals for alumni (mine does).
