I would have to agree with Moto... Going Mac was the best thing I've done from a computer standpoint in the last 10 years. Certainly the PowerBook G4 I bought was dog slow compared with the PC... but once Apple moved to intel, their Hardware and OS integration offer a user experience that cannont be matched by other platforms.
My primary reasons for moving (switching in Apple parlance) were to run Logic Pro and because I was fed up with having to run so many AVs and malware checkers, a firewall and spam guard all the time... Also I spent more time trying to fix problems with the stupid thing that actually getting any work done... I was fed up with Windows... so I took the hit and bought a Mac... I wish I had waited a little as the PPC was such a poo CPU... but wow, my MacBook Pro is a little box of Joy :-)
Like Moto, I also am prepared to spend money on software I use, and in my field (Music) comercial software on the Mac is often far superior to that which is available on the Windows platform.
I have no difference between the amount of Free software available for the Mac Vs any other platform... All Unix stuff compiles without problems... plus Apple have seen fit to include a fully integrated X11 server, so *nix GUI based apps run as if first class... very nice :-)
