UT-PB1 e-reader out for a step-and-repeat at the e-Book Expo Tokyo this year, but kept some important details under wraps. Now the tablet e-reader is ready for its official coming out party. The 7-inch, color touchscreen Raboo UT-PB1 is set to launch in Japan on August 10th, retailing at about ¥34,800 (that's $444) and packing 600 plus "pre-viewable books." There's an Android OS running on an unspecified dual-core CPU under that book-mimicking surface with the company's own UI slathered all over it -- so there'll be no tablet-esque shenanigans here, yet. The 400 gram (14 ounce) handheld also comes furnished with 8GB of storage, WiFi, Bluetooth, microSDHC, support for various video and audio files, and packs basic web and email apps. Sound like a dedicated reading device to you? Unfortunately, it only plays nice with the XMDF e-book format, so if you're interested in picking one up, you're gonna be tied to the Rakuten E-Book store. Check out the video below for a glimpse of the non-tab in action and maybe even a little dental training doll cameo.
