Acer's today announced its CES 2012 offerings. Up first, the Aspire Timeline Ultra. While we do not yet have full details (or even an image!) we do know that the ultrabook will come in 14 and 15-inch varieties, with as-yet-unspecified Intel Core i CPUs, Dolby Home Theatre v4 Surround Sound speakers, and they will feature Acer instant on, and be rated for up to 8 hours of battery life. We also hear that the Ultras will be just 20mm thick, and will have both HDMI and USB 3.0 ports. Acer says the Aspire Timeline Ultra will ship sometime during Q1 of 2012. There are no other details or pricing, but we'll keep updating as we get more information.
