That picce of info is not known. Not like my Droid 3 (Motorolla) is a gem. 3 minute boots. Possibly 4 minutes. If I had the latest hardware though, my opinion of Android regarding reboots would probably be different.
Ahh that makes sense now... using a droid 3... I had one and it was nothing special at all. Even the droid razr is far and away better than the droid 3.
I didn't watch the entire bb10 video... too long, but it looks competitive with a high end android phone, appears to easily best ios in terms of features like multitasking... but to be WAY better than android which is mature and powerful, especially jellybean or a touchwiz rom seems like a stretch.
Basing your opinion of android on using a droid 3 is definitely missing out as it is way behind current phones.
