Ubuntu: Watching Netflix on Linux has always been a pain, since Microsoft Silverlight isn't available on Linux. The unofficial Netflix app for Ubuntu makes it easy to install Netflix and start watching movies right away.
The app basically packages WINE and Netflix into a simple little desktop app, which you can install through a simple Ubuntu repository. It'll take up a fair amount of space on your system, but at least you'll finally be able to stream movies to that Linux-based home theater PC, or your laptop running Ubuntu. All you need to do is run the following two commands, one after the other:
sudo apt-get update && sudo apt-get install netflix-desktop
After it finishes installing (give it a few minutes), you can hop into Ubuntu's Dash and search for "Netflix Desktop," or launch it from the terminal with
netflix-desktop. The first time you launch, it'll do some extra installation work, but when it's done, it'll launch in full screen mode and let you start watching movies. To exit full screen mode, just press F11 (though you can also exit the app entirely with Alt+F4).
Right now, it looks like you can only install the app on Ubuntu, but hopefully some nice folks will find ways to install it on other Linux-based systems. Hit the link to read more.
