None of my PCs will run the premium version of Vista as they are configured leaving me at a crossroads . As I move to dual processor system, should I stick with Windows and go Vista? Or since I have to buy a new computer anyway, should I go with a Mac?

I'm not much of a PC gamer (I prefer my PS3). I use my computer for word processing, light spreadsheets, presentations, web browsing, digital photos and of course, e-mail.

In a recent address to a Mac developers conference, Steve Jobs mocked Vista as an OS X knockoff. If this is true, are the secuirtiy claims of Mac worth making the switch, especially with the ability to run Windows on a Mac via boot camp or Parallels (an emulator which runs Linux, Windows, etc. and has gotten great reviews) is it time to consider a switch.

Thanks in advance for your thoughts.
