Got the Roku box back when they had the Roku HD and I do love my little box. The only things that would make it better is if CBS had their stuff on a Roku channel and if HBO Go was a stand alone service like Netflix and Hulu Plus.
Yes at first I missed cable and seeing some things in the first run, but by all that is geeky I've got such a back log of shows and movies to watch I wouldn't have time for cable if I had it. Tons of anime on Roku while it was hard to find on cable except in a block on a few channels maybe once a week. Life without reality shows and contest shows is so nice.
