I must say i loooovvveeee my laptop. I never had a problem with it (knock on wood), and if i did it was a no brainer to fix. Viruses don't bother me, nor do i have to mess with ad-aware software etc. My start up programs include Finder,iTunes,Airport and thats it. No annoying anti-virus, Zone-alarm, or whatever programs to hog my CPU or RAM. I just turn it on and get going. Powerbook G4 running Mac OS 10.3.9, soon to be Tiger. I'm not saying Toshiba, Sony, or IBM are not worth getting - they are all solid machines. I worked on all of them, It's the Windows Operating System that has gliches in its matrix and is prone to be attacked online. If you dont have a good firewall (hardware) and other programs to keep you safe from being online, your screwed.
Get a Mac and get going!!!!!!!!!!!!!!!!!........just my opinion.
