I think for most people 720p would be enough, for streaming purposes anyway. According to wiki (yeah, I know... but it's an easy reference
) a bitrate of 20Mbps is enough to deliver 720p @60fps using H.264 codec. Now, I agree, that's still too high for most Internet connections, but we're not that far off.
As for the non-tech savvy - well, most of them managed very well with digital audio, and Apple made it easy and convenient for the media to be mainstream. Why should video be any different? I think with the right hardware and distribution systems in place, even the non-savvy will find it easy.
