buttchip, I was a LONG time palm user, from the flippy 300, to the 600, to the 750p, then to the Pre, and I think there may have been another one in there somewhere. I loved them all. I never got an iphone, partially cause never was too much of an apple fan, but MAINLY cause I could not pull myself away from a physical qwerty. And for some reason, although I can't put my finger on it, just never had an itch to try an Android phone.
My wife got a WP7 a little while before I did, LG Quantum, which has the phisical qwerty. Even though I was wanting to make the change to the WP7 world, what I mainly wanted was the bigger screen. So I reluctantly went with the Focus (no qwerty). And you know what? It's not near as bad as I thought it was finally switching over to the on screen keyboard. Probably because the WP7 has a LOT of cool tricks and shortcuts that does not transfer over to a physical qwerty.
Things I could easily do on my focus, I could not do on my wife's physical qwerty. Just a couple of examples, when the phone knows your typing in a web address, it will then give you a [.com] key, and if you hold that key down, it will then pop up [.net] [.org] [.edu] options (why no [.gov]? who knows). if you hold down the 1, it will pop up 1/2 1/3 1/4 options that look a LOT nicer than just typing the [1][/][2] keys, they actually look more like fractions (and similar options when you hold the 2,3 or 0 keys). The locks are much easier to use for CAPS and numbers and symbols, and a nice touch and slide feature if you just need 1 quick number or symbol that automatically switches back to the regular keyboard.
Anyways, I hope this helps you out with your decision.
