I am less sanguine about this product, which also goes on sale Thursday, for an introductory price of $5 (the regular price is $20). I also tested a new companion Parallels Mobile iPad and iPhone app, which allows you to remotely control both your Mac and Windows running on your Mac. Parallels Desktop 7 lets Windows programs, like Excel on the left, appear on the Mac as if they were Mac programs, without the Windows desktop.
