As expected, several laptop manufacturers have released the first of the Core 2 Duo (Merom) based laptops today.

Dell, Toshiba, Samsung and Alienware announced laptop models which utilize the new Core 2 Duo processors.

Apple, however, has yet to announce a Merom/Core 2 Duo upgrade to their laptop line (MacBook and MacBook Pro), but several rumors suggest that these upgrades will come in September.

Historically, Apple's processor upgrades have been tied to Motorola/IBM's PowerPC upgrades which have generally been less frequent and less public than Intel's. With the switch to Intel, Apple may have to provide timely upgrades to remain competitive with Windows-based PC manufacturers.
