My reason for the poll is because my GF has the incredible and she says my X is too big. I have big hands, she small hands and can't understand why i prefer the X over the Dinc
I'm a smaller than average woman and when I first saw the X and tried it out in the store, I thought there was no way I could use the phone comfortably. But the Incredible, which I had intended to get, was on backorder and I needed a phone right away to replace my broken Omnia. So, I decided that while I was waiting for the Inc to get back in stock that I would use the X and then exchange it within the 30 days. After the first few days I was used to the size and liked the larger screen so much (I do a lot of web browsing) that I couldn't imagine exchanging it for the Incredible.
So, I kept the X and am happy with it (except for the multiple low volume issues). Occasionally, it's a bit difficult to use one handed but not enough so that I would go to a smaller phone. I guess it depends on what your GF uses her phone for the most, whether the screen size/features outweighs any difficulties using the phone with small hands.
My brother told me I was nuts for getting the X and it was way too big, I had the D1 from almost launch and he said that was too big until he got one (his first smartphone) then last weekend he played around with the X and was still saying it was a little big but not as bad as when he first held it. I think because he got to play around and saw the advantages over the D1
