Also with regards to
Vista v OS X v Unix/Linux.
Ever seen a Toshiba Laptop with a tri-boot setup that involves all three??? ask me for details ;D ;D
Though i did kill a work computer trying the same thing. The tech dude was like \"why the F**k is the dell pc trying to boot a Mac OS?\".......
I would take Vista over all including XP but then again i have the hardware to run Vista properly.
The one thing i love about the Mac ads and everything, there is no viruses for mac because noone can be bothered making them. When you webcam breaks you lose your entire computer to get it fixed, PC you simply remove the USB connector and BOOM!. If i want to upgrade any part of a PC i don't lose warranty and have a wider range of parts.
  Instead of creating a webpage in a few hours matabele, I can create a top end programs using Visual Studio .NET. And aftewards I can play any game i want.
 Sif get a Mac they are pointless, everything can be EASILY done on a PC and to a lesser extent a Linux distro.
