I bought this
 

After reading some reviews and not being able to wait on CDMA devices I pulled the trigger on WP7. Since I can't stand virtual keyboards and the Dell Venue was nowhere in sight, I settled on the Quantum. I read a bunch of reviews and they all looked like this would be a fine device, so I'm happy. It hits all my important points, which is good battery life (compared to the others) and a physical keyboard. That's about as picky as I was. So ask me questions and stuff I guess!

Points of note.

Here's a review for a device that's supposed to be the same phone except without the keyboard:

Supposedly the big update coming is also going to address the landscape issues people are talking about. Honestly so far everything I've popped the keyboard out to do has rotated to landscape, so I don't really know what the problem is.

Congrats and I hope you enjoy the phone. I haven't actually gone to the store to look at that one since it wasn't available at the same time as the Surround and Focus.

I have the Surround and I like it. There's things I miss about Android, but hopefully the update will fix some of those and developers will continue to be fast and releasing apps.
