What to do with Kindle Fire HDX?

So I got a Kindle Fire HDX for Christmas yesterday. I am so far underwhelmed with it, especially in app selection and overall interface (took me a while to figure out how to get directly to the app store, for instance). So I am wondering what would be the best method to make this something I will use more? I am currently almost exclusively Apple, so this is my first move into android, even if it is Amazon's special variety. What is the best way to get google play on it, or at least a better app selection? Should I root this thing and try to put stock android on it? Is that even possible? I mainly got it to play around with, so nothing is really out of the scope of what I would do with it. Just thought I would check here first and see if any current owners have some good ideas on what to do to spruce this thing up. Thanks in advance.
