Let me shed some light....
Windows sucks. However if you ever want to update the laptop stick with windows. If you want to not get infections, don't be stupid. READ THE STICKIES HERE and you will get maybe an infection or 2 yearly.
I don't like MACs. They are annoying and easier to destroy imo. Macs can easily get infections, if you have seen the b/s commercials about how PCs get infections and macs don't... well first off a PC is a personal computer nothing to do with windows. (Morons made that commercial i assure you). As for the pains in the *** of windows, use good software; recieve great results.
For instance... remove norton, mcaffee, w/e firewall they give you, AOL, and WMP. Install avg / avast, zone alarm, AIM (if you must use aol instant messenger use AIM 6.x), and spybot S&D. Winamp for music playing. If you'd like to hear more.... PM me or something.

PS
if you ever want to transfer files from computers do NOT buy a mac. Why? 85% of the world is unix and windows.
