US ONLY (unless you VPN/spoof): VUDU, the streaming movie and TV service, is trying to cut Apple out of the profit picture by circumventing the App Store with a web app. This way, Apple doesn't get money off of VUDU's movie sales and rentals.
You can just access VUDU by going to Vudu.com in Safari. The new web app uses Apple's HTTP Live adaptive bit rate streaming to maintain good quality streams but movies are limited to only standard def streaming (TV shows fluctuate in quality depending on internet connection). There's over 20,000 movies to rent or buy on the website and all previous purchases will be instantly watchable. I never prefer a web app over a native app but VUDU's take isn't so bad.
