The new HDX format is great. I traded in my BR player for a 6mo experiment, so far Im happy. When a movie becomes available for rent, I can tell my box to remotely download it from any pc, then watch it whenever I want. For me, this is a replacement to Netflix (got tired of waiting on new flicks) and a BR player. As far as streaming goes, my Directv HDDVR does that.
You gotta remember, Vudu is still young, and those apple fans can say what they want about Apple TV, but at the end of the day, the AppleTV movie PQ aint so hot. Jobs also just stated that itll still be a "hobby" in 09, so its another mediocore apple product I wont buy.
And BTW, who the hell cares about watching you tube, thats pretty lame reasoning. Vudu has one purpose, watching movies without having to leave your home, and at their current pace, theyll have more HD movies than Apple soon.
