Query: The best PMP in the market!

I've had my Archos 605 for two years now and its the best portable electronic gagdet I've ever bought. Surf the net, download movies, show, music, pictures, or your own video in any format. Never have to worry about compatibility. Also, purchase the DVR you will be able to watch your stored movies on the big screen as well as recording your favorite shows and taking them on the road.
