New leaks from sources on Tuesday hinted that Dell's replacement for the Adamo will be more overtly distinct from the MacBook Air that Dell had originally tried to chase. Rather that go for similar sizes, they would start with 15.6-inch screens and focus on being the thinnest at that size. They would use Core i5 and i7 chips, although CNET's tips couldn't glean whether they were low voltage or full power processors.
