BB will get a few nostalgia buys, but once they realize it is Android in disguise they will just go back to Android.
Personally love my Lumia 920, but even buying it a few months after launch it was difficult to find even a simple black one. I really wonder how many would-be WP8 buyers were simply turned away at the door, and so they ended up with Android or iPhone. Nokia makes some great phones, but unless they can get volume out there then they are still a bit doomed. WP8 is a great platform, with a good app selection that is growing quickly, and I don't regret my purchase. The only thing that will keep me from getting a WP device in 2 years when my contract is up is if they have Wallet working yet. It is a great idea, and very secure implementation, but if it never gets off the ground then I will gladly sell my soul to whoever lets me get rid of my wallet.
