Feature - Choosing My Next Smartphone

I've been fighting this battle for far too long and it's about time I come to some kind of decision. I don't know where I'll turn, but I really want to buy myslf a new smartphone. After migrating over from a conventional phone to a smartphone, there really is no turning back. The simple functionality of a dumbphone just doesn't cut the mustard for me.
Some of the Top Contenders
Although the Apple fanatics will hate me for saying this, I've already decided that I'm not going to even consider the iPhone 3G. This isn't to say that I won't have some sort of iPhone in the future, but the current incarnation isn't really what I want.
In terms of criteria, I don't think I'm being terribly picky, but this could be the source of my indecision. For frame of reference, I'm currently using an ancient T-Mobile MDA Vario (HTC Wizard) running on Windows Mobile 5. Yes, I'm that old school and it's time for an upgrade. I'd prefer to keep a touchscreen around, though that's not really a requirement. I'm open to different operating systems, but I cannot live without a hardware QWERTY keyboard. I also need a good "Today" screen.
Regarding preferences, I'd like a decent resolution camera that can do video, an adequate email client, a decent web browser, and expandable memory. I'm willing to budge on any of these if other features win me over. Let's see who is currently sitting at the top of the heap.
