I don't think OnLive is nearly advanced enough for it to be used as a selling point on new devices.
I am sure we're headed to a "cloud-based" home gaming market, but while I respect how far OnLive has come since it debuted, it's still got a very long ways to go before I view it as an incentive to buy something.
On the other hand, OnLive's new MS Office offerings idea is pretty interesting.
Correction to my above post using the link provided works now. It was listing as out of stock before but is available again. I cant wait to replace my roku 2 XS
