OP, If you already have the stance that you've taken, I would say don't buy at all simply because you seem to be a bit more closed-minded than even I am - and that's saying a lot.

I'm willing to let Nokia prove themselves to me; however they will have to do it on my terms - meaning I want to see the stuff that I've been patiently wanting in a platform for a while.

Will I get them all immediately? Nope. Will it happen before I'm likely going to lose my patience? Perhaps not. But to already question as deeply as you have and feel like you're part of a beta test... then pull back from a lot of other products as well.

I've been feeling like a beta tester for ages due to the nature from all things from OS to e-mail to (now) phone. Enjoy the ride or just sit back and decide when you want to jump in.

Up to you. Good luck on making up your own mind on your own terms. That's what I'm personally doing.
