There is enough information on here to learn about the technical aspects of this phone, most of which is over my head. I use it to talk and sometimes take photos.Here is my 2 cents:1. The phone feels nice and solid in the hand, something I've missed since my old V70.2. It is very slim and this cannot be overrated when you're wearing slacks or a suit jacket.3. People who complained about the smallish size of the keys were correct - I imagine I have smaller fingers than many guys and I frequently miskey, especially the menu key.4. The screen and interface is a huge leap forward from my V557. Since I have always had Motorolas, I can't comment on its relative merits.5. Friends of mine who owned RAZRs and complained that they felt like they were talking on a Hershey's bar instead of a phone like the KRZR much better. It is a lot narrower.6. The camera is excellent. Really.7. Buying it unlocked required a little fooling around with the OS and settings to get it working fully featured for AT&T.; I don't remember exactly what I did except read a lot of stuff on the internet and spend about a day futzing with it.8. Those who complained about greasy fingerprints on the glass cover were also correct. My phone has not looked clean since I first touched it. But that doesn't matter, because....9. One week after I got it the glass cracked - in my pocket. I still don't know how it happened, but it spread across the phone in a few hours. It apparently is so delicate, I wonder if you could call it a design flaw.However, bottom line is that it works better as a phone than any other I have had to date, and I am pretty satisfied.
