I have to say I don't get some of the Lumia 920 reviews that went on and on about how heavy the phone is. One even said you can't hold the phone in one hand for any length of time.
I can't even tell the difference between it and the Lumia 900. Plus with the (practically) required case on the iPhone 5, it is often just as heavy. The Lumia 920 will be the 1st phone I'm not going to even bother putting in a case or put a screen protector on. I feel its build quality is good enough to not require it.
Anyway, great phone. It feels very slick compared to the Lumia 900.
