I came from a Samsung Focus Flash that was having problems dropping calls when connected to my microcell. After 8 months of dealing with that, AT&T let me pick a new phone at the 2 year price. My options were L900, Focus 2, and Titan 2. Not much of a selection, but I knew what I wanted.
In order of importance this is why I love this phone.
1. It works, after 8 months of not having a working phone, this is huge.
2. It is a drop dead gorgeous phone.
3. It's a Windows Phone.
I do have a few problems with it, like the "sticky" buttons, and the lack of Tango (grrr). BUT compared to my Samsung, this is a million times better. Plus Nokia seems like they really care about their customers. If anything is going to bring this phone down it will be AT&T.
