I had the Dinc for about a week (after waiting, and paying 2 months), I then had too many call quality issues. The only thing I liked about the Dinc was the UI. I have my X now, I've rooted, unrooted, and also been back forth with the leak - With LP and fancy widget I pretty much solved the UI issue. The call quality is real good on the X, THE main reason I've stuck with Verizon for so long.
I was a Storm 1 (in a otterbox) - Dinc - X user, so the size at first seemed large, but after only about 4 or 5 days I got used to it. Web browsing is so nice on the X, and I have large hands so typing is a breeze. I was in a VW Store to pay my bill over the weekend, curious to find a torch and play with it I put my phone up to a Dinc, its so much bigger in comparison - first time I honestly did a side by side comparison, but I'm sticking it out with Moto, much better build in and out imho.
