Well I'm very pleased thus far with News Demon no complaints at all. There are cheaper options out there but I do like a bit of security and I think with them being one of the big names you get that.
In other news my Google phone HTC Hero is great since it has been updated to Andriod 2.1 and the Meridian Andriod Video / Media player is very solid.
This combined with Win FF works fine as a MP4 player. I've found I still get lip sync issues but if I kill meridian with Task Killer it works like a charm.
