Like drivebyacct2 said, you can get content from Google Play. But the really funny thing is, you can get all of that from Amazon on any Android tablet. I don't understand how people don't realize that all the Amazon apps on the Kindle can be installed on any other Android tablet. This is exactly what I did with the Nexus 7 - you can get the Amazon App Store, Kindle app, etc.
I find Netflix and Amazon Instant complement each other nicely. I watch as much of a series as Netflix has, then I can watch the remaining seasons on Amazon Instant. Amazon Instant also gets me current shows, like the newest Doctor Who episode.
I've tried that, didn't work on my Galaxy Nexus. It installed but looked squashed and couldn't log-in to my account. It's obvious that it wasn't designed for multiple form factors. YMMV of course.
