We got to play with the Viliv S5 at CES, and now the gang at UMPC Portal have some detailed impressions they'd like to share with the world. The haptic touchscreen device has "one of the best" on-screen keyboards this reviewer's seen, although it pales in comparison to a physical keyboard. Other minor issues include a lack of a microphone and physical mouse pointer, though you could quite conceivably get along just fine without 'em. That said, this bad boy apparently has "an overall good feeling" that makes the reviewer want to use the device more and give the touchscreen typing situation "a chance." Kudos for the "incredibly impressive" battery life, and not even the lack of 3G and an SSD prevents him from declaring it "the best pocketable UMPC," one that "raises the bar." But that ain't all -- check out the video after the break for the handheld in all its glory.
