Virtualization software from Parallels has done a remarkable job of letting Mac users run Windows software on their Mac right alongside their Mac programs. Windows programs simply appear as Mac programs. Now they've done something similar for the iPad. Their new app and service, called Parallels Access ($79.99/year), lets you run Windows and Mac software programs on your iPad. Your computer needs to be on and accessible via remote connection, but the genius of the Parallels app is that these programs act like iPad apps, such that you can control all of the functions in the same way you would any other app using all the gestures that are so familiar to you.
