Apple bumped up its line of Macbooks this morning, forgoing the company's usual brand of Cupertino keynote fanfare.

The most significant upgrade to the company's 13-inch flagship notebook models is the eagerly-awaited (and much rumored) move to Santa Rosa architecture, bumping the chips from Intel GMA 950 up to Intel GMA X3100, a move that boasts 3X graphic improvements, though gamers looking to make the jump to Leopard will have to keep dreaming--these systems still won't be capable of running those high-end 3D games.

The base model ($1,099) is getting the bump up to a 2GHz Intel Core 2 Duo T7300 processor, with 800 FSB support. The midrange and high end Macbooks, meanwhile, now feature 2.2 GHz Core 2 Duo T7500 processors. For those looking to spend a bit more, the 15- and 17-inch Macbook Pros can now be upgraded to 2.6 GHz Intel Core 2 Duo T7600 processors, for $250.

The low-end Macbooks still feature CDRW combo drives--rather than the DVD burners that are now standard on most computers. Highend Macbooks ($1,499) still ship with 1GB of RAM.
