Played with one at the mall in Syracuse, NY today in the AT&T store. Had a Beats by Dre audio box set up around it with all of the Beats By Dre headphones (not the $99 earbuds though) available.
For those who have not seen the display in person......it is AMAZING!!!!!!! Don't know about the iPhone display, but it CLEARY makes any Samsung phone's display look like crap!!! Super LCD 2 FTW!!!
Other than that, it was very responsive, thinner than I expected but easy to hold. I don't have big hands but I was still able to hold it and swipe using one hand. The camera is very,very quick when it comes to taking pictures. Overall, I loved the phone, and I can't wait until the EVO4GLTE comes out for Sprint because that is the version on the HTC One X that I want.
