Hi. Right now I am a Windows user, but I really want to switch to Mac. Soon! I am going to school and I will continue to for the next few years and I therefore need a portable computer. All it has to be able to is handle iWork, iTunes and Safari (I don't game since I have a PS3). I really want the new Air, but I am afraid it will slower than a MBP 13" 2.4. Also, at least where I live, the Air is a fair bit more expensive than a Pro and I don't know if a little less weight is worth the money?
