This is something new??? You can do the same thing with an HTPC. I built 3 high powered pc months ago at work, have it connected to a 52" Sharp Aqous 1080p 120hz TV via HDMI cable, with the top of the line logitec webcam and a Good Mic. I built 3 and we use skype to video conference between 3 of our locations. Plus we can still use it for other purposes. So this just seems like a waste of money if all you can really do is skype with it.
Plus with an HTPC you are not stuck to just one brand of TV.
