What I have found nice about the Chromebook is that it is simple. Don't have to fuss with updates, don't have to have all these different programs (Adobe reader, Adobe flash, Java, Office, Windows, Chrome, Firefox, etc.) fighting to run their update (hourly Google? Really?)
For people who portability means "moving from living room to the bedroom" or occasionally using it in a remote location where often WiFi is available (it is in all the meetings I go to), the Chromebook works out pretty good.
For Microsoft, FUD is nothing new. This commercial, however, is a more negative FUD and that negativity leaves a bad taste in the mouth. Unfortunately, for Microsoft, that bad taste is overshadowing the legitimate limitations and arguments no matter how well construed.
