LAS VEGAS--Acer unveiled the Aspire S5, which it boasts is the world's thinnest Ultrabook.

The Aspire S5 is the second ultrabook that Acer announced today at its press conference ahead of the official start of the Consumer Electronics Show. With ultrabooks looking very similar in size and shape to each other, thinness has been on the key differentiators. Acer boasts that the device is only 15 millimeters at its maximum point.

Like the Acer Timeline Ultra, it offers an instant-on connection, allowing it to turn on within 1.5 seconds. The device will also get the same access to cloud services from AcerCloud.

It weighs less than less than 3 pounds and is built with a 13.3-inch LCD display. It will also have an HDMI port, USB 3.0, and a Thunderbolt connection.

The Aspire S5 will start shipping in the second quarter.
