I mentioned Boxee the other day, which we are enormously pleased with at my house. The newest alpha release of Boxee now gets Netflix (so long Roku player!), the WB, and improved Hulu and YouTube. Yowza.
We just bought an AppleTV after months of having to sneakernet our iPods to the Family Entertainment Center whenever we wanted to watch iTunes Store content. I must say I'm impressed. Got it to work with the 550 Harmony Remote, too.
Tomorrow our Roku Netflix Player arrives. We have the six-disk-at-a-time/unlimited Netflix plan so we'll be able to see unlimited "Instant Play" movies and shows. I know some people are saying that there's not a lot of "good" stuff to watch instantly, it's sub-DVD quality, no HD, yadda. But we have pretty esoteric tastes here and have been delighted with the lists of stuff that is available. Plus, can HD be that far around the corner?
