It would be pretty unbelievable if BB10 could run Android apps directly.
I just want to note that BB10 is based on QNX, an old time (proprietary) system that is big in the embedded world (think cars, planes, robots, ...). Android is based on Linux and iOS on Darwin (a distant cousin to FreeBSD). All three systems are based on
Unix.
As a Unix enthusiast (and to a large extent, a Unix professional), this made me happy!
