In my view macs are for people with more money than technical skill. They work out of the box and for most users, they are harder to break than a windows pc. Myself, especially now that they are basically wintel machines running osx, I wouldn't spend that much for a closed system intel pc. In fact the only way I will ever buy a macintosh is buying one to run MORPHOS on.
As far as windows...
Windows lacks good security but that can be easily fixed with a little know how. Windows has the most applications and games too... Wintendo basically. I keep windows just for games and video editing, the rest I use linux for, and of course there is always
AMIGA!
