I recently upgraded my internet broadband speed to 60 down and 5 up. I also just got a new Roku XD. I have to say, with my Slingbox SOLO, Roku, Charter HD cable, and Motorola Droid (1), I couldn't be happier with the results. Everything just seems to jump off the screen (Samsung 42 inch HDTV, laptop, or Droid). Now, if Netflix would get a better selection of HD movies, I would cancel all my Charter movie channels.
