I tried to get a free trial of Netflix yesterday to test out the "Watch Instantly" stuff on the new Xbox 360 addin but they wouldn't let me because I was a previous customer (albeit, over 5 years ago, so remind me to point out the idiocy of that). Anyhow, so I signed up for the cheapest subscription I could just to check it out.
The selection is crap, but you netflix subscribers probably already knew that. The quality was alright, but with the ultra-limited selection, I'm not even close to giving up my Blockbuster subscription.
