Three Dees and Four Gees. That's the Evo 3D. But it's more than that: The screen's a killer 4.3-inch, 960x540 auto-stereoscopic display, meaning it's almost as high-res as the iPhone 4 and pulls off 3D tricks without glasses (like Nintendo's 3DS).
Inside, you've got a dual-core 1.2GHz Qualcomm Snapdragon 8660 processor, so it can play back (or capture!) 720p video in 3D or 1080p video in 2D. (And Android 2.3 means you'll feel the full snappiness of the chip—depending on how heavy the latest version of HTC's Sense interface is, which now has a "carousel" desktop.)
