Finally! After 2 and a half years with a crappy pc laptop I got a beautiful new Macbook! My friends are all jealous. The only bad thing is that the Macbook will atract too much attention and I'm kind of low-profile, but it's worth it. So, I just have a couple of questions: I noticed that the available disk space was about 55gb, when the hard drive is 80 gb, is this normal? Does the software and OS use so much disk space? Also I wanted to know which features it has that I should know about to make the most of my computer. Thanks a lot.
