I've owned Windows Phones since their conception. HTC, Samsung, Nokia. So far my best experience has been with the Nokia 820 (ATT). It's the perfect size......weight is just right........you know you have in you possession and in a situation you can heave it at someone and it will hurt. Fast, yep, sure is. Also the casing is remarkable or shall I say unmarkable. It doesn't scatch with everyday use. I drop it a few days ago as i was getting out of my car....not one ding. My sister inlaw drop her Sumsung S3 the same way and the screen cracked. I'm saying it's bad enough that that Windows Phone dosen't get the credit it deserves ATT sales people hardly know it exsist.....a shame for sure.
