Acer kicked off the Ultrabook flurry at CES 2012 by unveiling the Aspire S5, described as the "world's thinnest Ultrabook", and the Aspire Timeline Ultra. And now, the Taiwan-based company has released yet another UItrabook into the wild - the Acer Aspire Timeline Ultra M3.

The M3 adds dedicated Nvidia GeForce GT640M graphics to the party, as well as offering a DVD optical drive in its 2-spindle setup. And it still manages to come in at less than 20mm thick.

Other specs include a choice between SSD only or SSD/HDD hybrid hard-drives (with the SSD part ensuring a fast boot-up time of less than 2.5 seconds), a Sandy Bridge Intel Core processor, Dolby Home Theater v4 with premium speakers, 8 hours of battery life and a 15-inch display.

"The ultra-thin profile of the M3 delivers a minimalist, modern look," Acer says. "The stylish black cover is made of an aluminium alloy that adds to the sturdiness. The full-size chiclet keyboard with a numeric keypad makes typing more comfortable and increases productivity."

The Aspire Timeline Ultra M3 will hit shops in March 2012; no word on pricing as of yet.
