Anyway...
As Genki already stated, Apple always overprices Macs. You're paying maybe around a +$200 USD premium, or even more.
I do give credit to Apple's marketing.
They seem to appeal to the "non-computer" savvy user, however everything in OSX can be done similarly through windows or linux.
Windows, the most common operating system for Personal Computers, and it'll likely stay like that way for awhile. Especially since it is the best OS for gaming right now. Despite quite a few problems.
(Many have ways around it.) I.E. : Viruses, use reliable antivirus and browse safely.
See, more malware is created for Windows because it's more common than OSX or Linux.
The point is to affect as many as possible.
If OSX were to be more common than Windows, it is likely that will be the main target for Viruses and such.
I would have to say, everybody needs to try Linux, at least once.
I had it on my old machine for about 5 months,
until changing to a new computer.
Many aspects of it, I really miss. Mostly, would be the freedom,
and the ease of downloading many programs.. Like Ubuntu "sudo apt-get
install x".
Seems as though I had the best video playback on Linux too,
maybe I hadn't experimented enough on XP though.
All-in-all, the 3 operating are pretty equal, depending on what your computer is for.
Imho, the price Apple is making you pay for a system with OSX is... much.
