Epson Moverio Video Glasses
We're still not convinced that they're appropriate for use in public — or anywhere else, for that matter — but if you're unconcerned with appearances, these Epson Moverio Video Glasses ($TBA) should provide as good of a portable viewing experience as you'll find. Powered by Android 2.2, the Moverio offers 1GB of built-in memory, an included 4GB SD card which can be replaced by cards packing up to 32GB of storage, Wi-Fi, built-in Dolby Mobile 2 stereo earphones, transparent lenses for see-through viewing, QHD screens that are the equivalent of watching a 320-inch screen from 20 meters away, and support for side-by-side 3D content.
