Pros: Keyboard works for me; screen is clear and easy to read (when it's lit); size is convenient; seems pretty tough; recharges quickly
Cons: software lacks a lot; microphone is all but useless for voice dialing; back-light time-out options
Summary: I can't quite remember now why I didn't replace my stolen Blackberry with another one, but the Q seemed a good idea at the time. Honestly, it's very serviceable, very good-looking, fits nicely into my hands, pocket, side of purse and I've found the keyboard easy to use. initial synchronization with my Outlook contacts was quick and straightforward. Initial setup of Bluetooth was difficult due to poor instructions on finding the "Discover Me" mode on the Q. Although microphone is adequate for speakerphone purposes, it is totally inadequate for voice dialing and I'm still trying to find out if I can use some sort of voice tag for each contact to mitigate that. So far, no luck. Up until now, Blackberry was the only cell phone/PDA I had used and if something happens to this one, I'll probably go back. Seems sturdy enough. I've dropped it once or twice without ill effect and carry it around in my purse without a cover. also, there needs to be a longer-time choice between "never" and "60 seconds" for back-light time-out. Finally, Microsoft needs to take some basic lessons from RIM as to PDA software.
