Pros: Helpful customer service and very reliable phone.
Cons: Verizon blocks a lot of the Razr's features (transferring photos to/from your phone requires the purchase of separate software). Also, their plans are quite limited.
Summary: I bought a Motorola razr 3vm about 2 years ago through amazon.com and the phone is great. The only problem I've had in that time was a sudden loss of service, but a quick call to Verizon customer service informed me that a simple restart was all that was needed (I had almost never turned it off before then and apparently that can lead to an unhappy phone). Now keeping in mind that this was my only contact with customer service over the phone (I guess that's a good thing), I found them friendly and helpful. I wasn't overly impressed with the service in the store.
The reception isn't as reliable as my previous phone/carrier (Virgin Mobile), but it's never been a problem. Some of my calls are dropped and reception can definitely cut out, but it's usually in an area that I'd expect it (basement of a 7 story building, ect). Unfortunately, this carrier is no longer the best deal for me (my friends have switched to US Cellular - making the verizon's IN feature pointless), but I would have liked to stay with Verizon had they offered a more flexible plan menu. Overall, this has been a positive experience.
