W-Zero3, Sharp just one-upped your azz with their new EM ONE handheld. This Windows Mobile 5.0 Pocket PC device brings 3.6Mbps HSDPA and 802.11b/g data to the game along with hot dual-sliding action under that 4.1-inch touch-screen display. Unlike Samsung's F520 dual-slider which combines a QWERTY and numeric keypad for making calls, Sharp's slab is a data-only device so they combine the QWERTY with a side-sliding navigation pad for scooting around the 800 x 480 pixel display. However, Sharp's EM ONE comes heavy on the chub at 140x70x18.9-mm compared to the F520's 105x54x17.4-mm or even Nokia's N800 which is about the same length and width but much thinner at 145x75x12.7-mm. The whole kit comes powered by a Marvell 520MHz PXA270 processor and nVidia GoForce 5500 graphics along with 512MB/128MB flash/SDRAM memory and miniSD expansion. The display boasts a rather anemic 65k color palette (albeit, the same as the N800) for viewing integrated 1-Seg mobile TV and WMV videos with WMA and MP3 audio playback supported by a pair of built-in stereo speakers. Rounding out the specs are Bluetooth 1.2, a 1.3 megapixel CMOS camera, stylus, and a 4-hour battery. On sale in Japan starting March 31st for ¥95,000 (about $797) without contract or ¥39,800 ($332) with 2-year commitment.
