i-mate is taking a pretty interesting approach with its newest range of Windows Mobile devices -- the WM6-equipped "Ultimate" range -- by shoving a full five models out the door, all differing only in form factor. Clockwise from the upper left, we have all five in purely theoretical, rendered form: the 5150, 6150, 7150, 9150, and 8150. The strategy makes sense, really; everyone wants a solid spec sheet, but getting everyone to agree on a single shape is an exercise in futility. With 256MB of ROM, VGA displays across the board, tri-band 3G radios, Bluetooth 2.0, and FM radios, the Ultimates definitely hold their own in the spec department -- the only question, then, is whether they've nailed the industrial design. The first model being shown all public-like, the 5150 slider, is admittedly an acquired taste, but some of the others really caught our eyes (7150 and 9150, we're looking at you).
