Running Android apps on a PC

I've started to look into Android emulators on Windows, but it actually quickly expanded to - ways to run Android apps on x86 PC.

Even though I knew there were quite a few options, I never imagined I'd come up with a list this long! I knew about most of these from before, but seeing it all in one place really makes you wonder what's the status of all these projects.

So without further ado, here are the (current) contenders:
