So I just picked one up today. It's ridiculous! The 3D part can be a bit gimmicky, but the insides of this phone are legit. 1.2Ghz dual core Snapdragon processor, 1 Gig of Ram, Gingerbread and all kinds of goodies.
It comes preloaded with The Green Hornet in 3D and a full Spiderman 3D game and they are both really impressive. YouTube 3D is also available by searching for YT3D within the Youtube app. Gimmicky or not, it's super cool and I have yet to get eye strain or a headache which I get at 3D movies on the big screen.
It's the fastest Android phone I've used in terms of snappiness in the UI. Sense 3.0 absolutely flies with this processor.
I'll post some more thoughts as I run it though it's paces.
