I had the Photon Q for a short while, having upgraded from an Epic 4G. The cam on the Q was pretty terrible, and although it was faster than my as-then ancient Epic, it wasn't as responsive as I would've liked; keyboard was awesome, though.
At any rate, I took it back within a week and ended up going with an HTC One. For the longest time I avoided touchscreen phones because:
1.) I'm a network engineer and I sometimes have to get on my phone if I don't have a laptop with me to email or do some basic information gathering/troubleshooting, and touchscreen keyboards weren't all that mature.
2.) I loved the tactile feedback of clicky buttons.
The One has worked marvelously for me, and I can type about as fast as I could on my Epic/Q. The bad news for folks like us is QWERTY sliders are no longer in demand or style. I'd say go down to the store, if you can, and play around with as many touchscreen phones as you can. Swype is good for texting, emailing, and basic stuff, but if you have to do any kind of remote work, it's worthless.
