Ultrabook token is here at CES? Wonder no more. Acer just tacked "Ultra" onto its revised Timeline series, pushing the actual boundaries of the definition. The new range -- which includes a 14-inch and 15-inch model -- touts up to eight hours of battery life, a "two-spindle" design, Instant On functionality, a chassis that measures 20mm thick, Intel's latest Core i processors, dedicated graphics and a slim DVD Super Multi optical drive. Those who buy in will get their choice of HDD or SSD and an HDMI port, with shipments starting this quarter. Shame there's no price to pore over, though.
