Dell at a press gathering today briefly offered an in-person look at its Adamo XPS ultraportable. True to its teaser graphic, the system is overall thinner than the MacBook Air it's designed to compete against (0.4 inches maximum) and appears to rely on a unique, underside hinge to reach its dimensions. As with very early Adamo and Inspiron 11z teasers, the company didn't provide any specifications or release information.
