One of the application I installed straight away on the VAIO MediaCenter PC was Joost. And after playing around with it over the last hour, I have to say that I start to like it already. Yes, there is not yet too much content available on Joost, but the interface is really nice, it simply works and the quality of a lot of the videos is good enough, even on a HighRes TV.
I will share my experiences with Joost over the coming weeks.
