I agree totally. That is exactly why I thought I didn't have Professional because there is nothing obvious that's different from 5.0.1. Their ad is a little misleading... I thought possibly Windows 8 was included. Dumb me!
Upgrade now to take advantage of 70+ new optimization and performance features including:
OS X Mountain Lion with notification center,
AirPlay mirroring and Launchpad search support
Windows 8, Windows 8 Pro and Windows 8 Enterprise
