Mac OSX - 10.4 - Tiger

Ok, you can install Virtual PC then XP over it.. but you pretty much taking the best of the mac away.
You can get office, open office and most other stuff.
It very compatiable on the whole, except with pocket pc (but theres software for that too)

 

That's what I thought. It's hard to break away from the shackles.

 

Stupid Shackles. But that is the hard part, getting all new applications or trying to do Virtual PC.

 

Yes, that was what I was worried about when I switched, but it works itself out after a while (initially make sure you have a pc as well).
