We already have devices that allow video chat on a tv, this is nothing new and most people don't care about it.
I like your thoughts on this matter, but while I agree that it is true that video chat has existed before, I would make the argument that video quality has been typically "sorta crappy" and most devices that have offered this have typically been standalone type systems and haven't been something that could be considered a focal point for home entertainment, which I believe the Roku box to be exactly that. I'd disagree that most people don't care about it, rather, I'd believe it to be more of a case of inaccessibility and/or inconvenient accessibility to the video chat technology coupled with the historically typical lackluster performance I noted above along with the forced incompatibility/proprietary mindset of those companies that have offered this in the past. What I'm getting at is, can we be sure that most folks don't care about video chat at all, or should we consider that maybe most folks simply don't care for video chat as it has been offered thus far?
Last thought, while typing I remembered that when mobile phones started becoming a bit popular in the late 80's and maybe even early 90's it was common for me to hear people say something along the lines of how no one cared and/or needed to have a phone in their car, that it was ridiculous to think that anyone couldn't simply wait until they could stop to use a phone or pay phone, etc. Now it seems that nearly everyone from kids to grandparents "need" their mobile phone to be with them. I'm guessing that some people may have thought that a TV in the home was pointless since the local theater had entertainment and news already.
If Roku (possibly with a developer) were to offer an integrated, quality picture and sound, hopefully compatible, and affordable video chat solution, I'd be interested and I think others may be too - but maybe not. I can imagine that if the SDK also allowed access to this functionality that it may also be adopted by the video-blogging, podcasting, and lifecasting communities.
The last thing I need is people watching me as I sit naked in front of my tv.
Thanks! I liked that video. It'll be interesting to see where this goes and whether or not this is a solution that is wanted.
