Would the apps be able to run as background processes? It's a really good move by AMD. One that RIM probably should have at least considered (I couldn't resist bringing them up)
RIM tried to let Android apps run on BB. They had a lot of restrictions though, and I think the project ended up a flop. Not sure, though, is it still active? They had a lot a restrictions on which apps could be run, which Android features could be used, etc, IIRC.
As far as I'm aware BB10 is compatible with a large subset of Android applications.
This is somewhat true. An Android app won't install and run on BB10 but developers can repackage an Android app fairly easily and offer it in the BB store.
