WDTV HD vs Roku

I'm not sure how many here have both or have tried both, but I'm thinking about going from a Western Digital HD streaming player to Roku. I'm overall just ready for something newer and I think the Roku has enough options and tweakability on it that it's going to keep me happy.

How well does PlayOn work with Roku?

What about other Live TV stuff for the Roku?

PlayOn "plays well" with my Roku. Yes, there are a number of live channels for Roku, especially if you use PlayOn, and with catastrophegirl's channel list you can find tons of channels - over 700 and counting.
