Yeah I saw one of these on *auction site* a week ago for $625. screw that.
I'm almost tempted for the genuine $425 price, but the word is that the menus aren't very fast despite being quad core (there's a comparison video on youtube, might be rigged though), the battery isn't removable, and the back capacitive button is on what I call the 'wrong side'.
Also Jelly Bean and Project Butter killed it. The leap from ICS is a lot bigger than from GB to ICS, I just can't ignore that.
I recently dropped my S2, the gorilla glass is cracked up quite a bit in the bottom right but luckily not the actual display layer which starts nearby, and I'm a bit bored with it, so I am in the hunt for something new, but this ain't it. It's a shame because I want 4.5 inch 720 screen spec which the D1 Quad has.
