This is what I was saying three weeks ago..
"The term for this used to be "thin client", and yes it's not fair to look at the 770 as anything but a networked device. But, as a practical matter, it's too hard to use my 770 this way, and especially in a VPN connection w/ a windows pc connected to my wifi router. It can't really do this at present for a wide range of applications."

I am happy if I was wrong...
