Dell in a teaser on Monday raised the prospects that its attempts to challenge the MacBook Air weren't over with the end of the Adamo line. The company planned to launch a series of new notebooks using Intel's Sandy Bridge (2011 Core) processors that would be headlined by a new ultraportable. It didn't explain the plans, but it recalled the Adamo's image with promises of "beauty and brawn" in an "innovative new form factor."
