Excerpt: I returned my iphone 5 due to small screen. AT&T was taking for ever to reverse my upgrade option, so I purchased this phone brand new for $200 from a 3rd party. Having owned a SG2 (international version), an iP5, and recently a lumia 820, I can tell you that this phone hits the sweet spot and trumps all the other phones as a daily user.
Summary: Lets preface this by saying I was a BB user before this, so of course I expected to go into user shock. It wasn't as bad as I thought it would be. I did have to adjust to the keyboard though. After some time it became a little easier especially with predictive text...Swype feature was cool, I couldn't get the voice to text to work maybe because of the constant background noise in my car I don't know.
Pros: Learning curve wasn't as bad as I thought it would be
Cons: Volume for calls going out and coming in were poor.
