I never had one myself, but i have borrowed one from my friend. It has a way better style than any other laptop brand hands down. Even the desktop controls are cool and u can download coool applications for it. It has cool magnets for the ports, and it has way more security than a Windows platform.
HAving a macbook, the controls are a little more similar to your average windows computer. (as u might know using a apple desktop for the first time is a real challenge.)
Macbooks are more expensive but overall i say get 1! maybe even 2..or3...heck 4 and mail me 1 :)
Osx leapord came out recently so dont worry about a new operating system coming out

its small so its easy to travel with and with 2.0GHz i think it can handle a lot............
and in response to the poster above, Macs can get virii.
And Macs are just as commonly used as Windows.....with professionals. Your average person would just pick windows because they think its the best. It is very difficult to write viruses for macs, so that is an advantage.
