It is large. It's thicker than my HTC Titan, but I suspect it will feel really good in your hand. As it is now, the only surface contact I have when holding my phone are the edges.
I wouldn't mind giving up a little thickness for comfort holding the device. I think in the race to make things thinner we might have gotten carried away. Imagine a phone as thin as box board...now imaging trying to hold it.
920 has rounded edges that make it comfortable to hold. the sharp (jewel like!!) edges of iphone make it uncomfortable. Lumia 900 is very similar in how it feels in hand. Give it a shot and decide for yourself.
