I went there to buy SGS II or the sensation. Accidently saw the Evo 3D with the shopkeeper and then chose to buy it right away 
The S2 is no doubt one of the best smart phones around but it feels plasticy. I hated it in my hands. Not to mention the back cover
I could literally break it with one finger!
The touch response is just like anyother phone..didn't find any difference. But one i need to tell you, it has this wow factor for sure
ppl go crazy when they experience the 3D effects on a cellphone.
But one thing i don't like is the display. Its quite dull even compared to my old iphone 3g. HTC needs to work in this department.
