I just found out that next semester, my school is switching to Mac! Yay! All the instructors and staff are getting MacBook Pros, and each student has the option to get a MacBook Air to use (and take home) for the semester. Here's my issue- I already have a great MacBook! However, I think an Air would be cool to use... I just don't know what I'd do with it other than to mess around with, because my MacBook (White) has the disk slot, ports etc. that the Air doesn't. It also has great battery life... To make it short... should I get one or not? What would I use it for if I did? Thanks!!! PS- I just found that today when I went to download an app, to my dismay my school network had blocked the App store!!! They also blocked MacRumors! luckily I have an iPod . What are they getting out of this? Since when is MacRumors a bad site?
