Update: We were guessing this was a rebrand of something, and thanks to commenter Raikus it looks like this is a Smit MID-650, which eviGroup's Wallet was also said to be based on -- at more than twice the price. Also, we (well, you really) seem to have taken down Enso's site thanks to traffic. Oops! Hit that eBay link if you're desperate to Buy It Now®.
Update 2: The annoying demonstration video previously embedded, which Enso had provided, has been replaced by the original, nagware-free version courtesy of ARMdevices.net.
Update 3: Possible fraud alert! We got a tip from @PitchingAFit that there are some shady dealings afoot, including Enso not providing updates to those who have bought this thing. The eBay listings for the company have all disappeared and, well, some folks are getting worried. At this point we'd strongly advise against ordering one of these suckers until Enso clarifies the situation. There's a little more info on the current situation over at Multimediawerld.be.
