Running Windows on Mac

[TheTussinMonstr]

I need to run Windows for certain accounting software I use, but I have a few questions I need help with before I invest a lot of what little money I have right now. To run Windows with Bootcamp, your system has to be completely restarted and booted up in Windows, correct? In Parallels, I know you run Windows essentially within OSX, so would I benefit from also upgrading from Tiger to Leopard, then running either XP/Vista in Parallels? And lastly, heh, XP or Vista?

Bootcamp needs reboot and can only be used with leopard.
Paralells should work with both.
I would suggest XP if you use parallels becuse it needs less memory.

And a suggestion look at virtualbox (http://www.virtualbox.org/) a free alternative to parallels.
