Nokia Lumia?

Hey guys,

I've been really attached to Nokia Lumia a.k.a Windows Phone lately, and I was wondering what is honest opinion of the user itself. It looks sexy, its freaking Windows, have decent camera, cheap, and even comes unlocked. I'm considering to purchase one, and I really need concrete feedback as of why this is good choice and why is not.

Here is a fact about myself. I don't really use apps or play games in my phone. I currently own iPhone 5 (32 GB), and I really feel need for change. (poor battery life, poor network & phone calls, etc..) If you guys recommend Nokia Lumia, what model do you guys recommend?
