If you're buying a PC, you probably know that you're getting Microsoft Windows on it. HP, Toshiba, and other vendors all have their own pre-installed "crapware," but Windows is Windows, no matter how many docks and dashboards it comes with.
Google's Android operating system, on the other hand, has been taken apart and put back together again so many times that some products which use it -- like Amazon's Kindle Fire tablets -- barely resemble the "pure" Android found on Google's own Nexus devices.
pre-installed on the upcoming HTC First smartphone and coming soon to newer existing HTC and Samsung devices, is another case in point. But what is it, really?

The hands-on barely resembled the normal Android experience, at least until you launch an app. Even then, chat "heads" (icons of your Facebook friends' faces) and notifications of Facebook updates pop up and cling to the sides of the screen while you're in the middle of other things. Facebook Home also replaces the lock screens of the phones it's installed on, and uses your face (or equals sign, or whatever your profile pic is) as a sort of replacement home button.
On the other hand ...
