Acer S5 announced as the world's thinnest Ultrabook

Windows-infused MacBook Air rivals are getting seriously sleek

Acer has set the Ultrabook bar at CES 2012 by announcing the S5 ultra-portable laptop. The attractive MacBook Air rival is the world's thinnest Ultrabook at just 15mm at its thickest point

Acer has announced the S5 Ultrabook, on the eve of CES 2012, claiming it to be the thinnest ultra-portable PC yet.

The 13.3-inch MacBook Air rival arrives with a Onyx black magnesium alloy body, an Intel i-Series processor and is only 15mm at its thickest point.

The device weighs in at 2.97lbs, while Acer is also pushing the MagicFlip I/O, a flap at the back of the device which reveals HMDI, USB 3.0 and Thunderbolt connectivity when lifted.

The appearance of the Thunderbolt port is particularly noteworthy as, so far, the technology Intel created in collaboration with Apple has only featured on MacBooks and Mac computers. Thunderbolt promises connectivity speeds faster than USB 3.0 and Firewire, but there are currently few compatible accessories.

The device also has Dolby Home Theatre Audio and will wake from sleep in 1.5 seconds thanks to Acer's Instant On technology. The battery will also last for a few weeks while the device is in sleep mode.

The attractive looking Acer S5 device is likely to be the first of a slew of Ultrabook - an Intel-backed initiative to bring high-powered, low-bulk machines to challenge the MacBook Air - releases at this year's CES expo.

Each of those releases are likely to come packing some sort of thinnest/lightest/sexiest/most powerful claim so it's wise for Intel to get in before most of the announcements are made at the CES press day on Monday.

The Acer S5 Ultrabook will be available in the second quarter of 2012, so look for a release in around March or April. No word on UK pricing yet.

We'll be endeavoring to get our hands on the device when the showroom doors open at CES in the forthcoming days.
