Opinion: OnLive is a train wreck: 
The OnLive Desktop service shows just how wrong desktop virtualization can be.
With OnLive Desktop, you get a pure Windows 7 and Office 2010 environment that can’t interact with the device you’re using it on or the content available to that device; that is scaled inappropriately for the iPad’s screen resolution; and that is available only when you have a broadband Internet connection.
OnLive Desktop is available for free, which is no bargain given its overall uselessness.
Unfortunately, despite the concept’s clear appeal, OnLive Desktop’s Windows-via-the-cloud offering is too awful in its current state, and it’s a great example of why you can’t stick one operating system onto another without any integration.
