OS Smackdown: Linux vs. Mac OS X vs. Windows Vista vs. Windows XP

Computerworld throws together another great article when they asked four experts to lay out their best arguments in support of their desktop operating systems of choice:

• James Turner for Linux
• Michael DeAgonia for Mac OS X
• Preston Gralla for Windows Vista
• David Ramel for Windows XP

Each is of these guys are positive that their choice in operating system is the best and they try their hardest to convince you that they are right. These are not rational, disengaged reviews; these are opinionated essays meant to sway your point of view and I will say they do make some interesting arguments for their side.
When you've read all the arguments, you make the call by voting in their reader poll -- and of course your own arguments or comments are welcome.
