They had a working prototype that would run Android and Ubuntu side by side. Would work as a standard Android phone. But when you dock it to the desktop, it's a 100% capable Ubuntu computer, sharing resources with Android. That was perfect. It's the best of both worlds, I'm sure it would be a huge hit. Leverage both the Android mobile ecosystem + Linux desktop at once? That was genius. But instead they chose the greedy path and try to control all of it themselves.
edit: I just learned that Ubuntu for Android was not abandoned. It's still a separate project. They wanna release Ubuntu for Android first in mid 2013. And hopefully that will be a gateway to get Android users interested in the Ubuntu Phone which will launch in 2014.
No it isn't an app. It is actually the full Ubuntu OS running on your android device. The point wasn't for it to be a touch screen, the point was that you could dock your device and suddenly be using a full desktop OS with all your desktop grade applications.
Motorola were the only OEM to have interest in ubuntu for android.. they took it, and completely ruined it.[1] There was no greed on canonical's part. I'm not sure whether i'd prefer 'android+ubuntu', or this 'ubuntu for all the screens' (existing ecosystem with mature OS vs a real free, unified desktop+mobile OS), but they aren't dropping either, apparently. I do wish they would allow the developer community access to their builds, though. I want it now!
1. see webtop; also look on XDA to see how to partially restore it to canonical's idea.
