Well, searching on the web about this, i found out that most people are thinking: (mac os x + linux + windows) - rebooting = Leopard

The thing is that Apple is not talking about Boot Camp anymore. Now, they are talking about Parallels.

With Boot Camp you could boot in windows or in Mac OS X. With Parallels you can have a window with windows or linux in your Mac OS X desktop!

I was using Boot Camp just because i need a windows app for learning languages. So every time i wanted to practice i had to reboot my machine. Really insane!

I suppose that with parallels you have a slower machine, but as i said i just need ONE app from windows :)
