I have Macbook Air 2011 and I'm thinking of installing Parallels Desktop 7 for MAC. But the cost to download Parallels 7 ($80) and then there linked version of Window 7 , is bundled at $250!!! Seems very high, I'm just wndering the cost/value relationship? Is there a better way? Also, I'd like to run my Mabook Air together with a Thunderbolt display, magic mouse, trackpad, keyboard? Anyone do this yet and have any comments on this setup? Thanks!
