So, Dusty's school uses online books that apparently use a version of Adobe PDF that won't open on my iPad or iMacs. We tried leopard and lion.

Logged in to my work PC and the online book works.

So, rather than buy a PC, I figured I would either get a virtual software and run windows or bootcamp, but that means formatting the drive, right? Then I would have to fuss with reinstalling every thing again...

So, what's the best out there?
