Wine On Android
Wine on Android was first presented at FOSDEM2014.
Keyboard Issue
Currently the Keyboard won't pop up by itself as you would expect it. A workaround is to install the app "Hacker's Keyboard" from F-Droid or the Play Store. Then open its settings and check "Use permanent notification". Now, when running Wine you can swipe down the notification area to enable the keyboard when you need it.
Bugs
There are some bugs on newer Android Versions, which might not be fixed soon.
