Asus today announced three more of the MacBooks Air-Influenced laptops, this time with larger displays and 'grown up' processors.U series, the line-up comprises a 12.1in design, a second with a 14in screen and a third with a 15.6in panel. All three will be made available - when, Asus didn't say - with a selection of Celeron, Pentium and Core 2 processors to choose from.

The 12-inch U20A, 13.3-inch UX30 and 15.6-inch UX50V are all based on the basic processors expected to be part of Intel's Consumer Ultra Low Voltage (CULV) effort and attempt to bring ultra-thin designs to larger systems, ranging from the entry 1.2GHz Celeron M in the U20A to the 1.3GHz Pentium, 1.4GHz Core 2 Solo and 1.6GHz Core 2 Duo in the UX30 and UX50V.The smaller two models use Intel's GMA 4500 graphics, but the UX50V gets a dedicated GeForce G 105M with 512MB of video memory.
