Anyone who is looking to use this as a daily driver is going to be very disappointed. None of the apps are fully functional and I don't think mobile data is going to work at all. Using it on my Nexus, I was able to look through the UI, open a few broswer pages ( but entering text into fields on the page seemed to only work for a few characters), and use the Gmail and Facebook app. The camera did not function, the side stage had not been implemented, 90% of the apps are simply icons on the desktop or a nonfunctional splash screen. This is intended for developers to get an idea of what they're developing their apps for. If you know what you're doing, you may be able to get a little more functionality out of it by making some changes via SSH/ADB, but it does not seem that there is even much you can do with that as of now. That being said, I was super excited to try it out on my Nexus 7 and only used it for about an hour before I reflashed Android back to it. About an hour was all I needed to do everything it had to offer. I do believe it has great potential and is something that can compete with Android, just at this point its nothing more than "This is how it might look."
