No (easy) way to get your own video on it yet. While the welcome message you get when you start it up tells you to go to the website (internet.sony.tv) to setup your own custom video links, there's no functionality available there (yet) to do so.
The weather and traffic page from Yahoo is nice, and it's handy having it right on the remote. The news they provide is fair... There's seven sources, one of which is their legal agreements, and while some are updated fairly regularly, the sports one hasn't been updated for over a month... The last story faded off it, and it's an empty channel now, at least for me.
I really want to like this, the integration with my TV is great, but it's not quite there yet on content and functionality. It is upgradable though (got an update when I first plugged it in, actually) so I'm hoping to see more and better things soon.
Still no luck on the web server on port 9784. There must be something there somewhere though...
