Major limitation for RemoteFX
If you're connecting to a virtual desktop it must be running Windows 7 Ultimate or Enterprise according to Microsoft tech requirements, which explains why I wasted an hour trying to get it working on Win7 Pro. Major bummer. :-(
BTW, OnLive is amazing. It sucks on a mobile device but on a desktop with a good network connection it's fast and very convenient. The picture quality isn't good enough for full HD but looks okay played in a window on an HD desktop. Very clever, impressive response times given what's actually happening behind the scenes.
