One personal gripe I've had with the Android runtime on BlackBerry 10 and the BlackBerry PlayBook is the fact that it's stull running Android 2.3.3 Gingerbread. While I understand why this was done, I was wondering if BlackBerry would ever be updating the runtime environment to support newer versions of Android.
As it turns out and as was announced at BlackBerry Jam Europe, BlackBerry will be updating the Android runtime eventually to support Android 4.1 Jelly Bean. That's good news for developers looking to port Android apps and end users who will be using them as it will provide a much better overall experience when using the ported Android apps.
