CES: Acer shows 'world's thinnest UltraBook', with Thunderbolt port

15mm thin, the Acer aspire S5

Acer is showing what it is calling the "world's thinnest UltraBook" laptop here at CES. According to Acer, at its thinnest point the Acer Aspire S5 measures only 15mm, and weighs a mere 1.35kg. It manages to stay slim by hiding its I/O ports in a flip-out flap at the rear (which certainly beats going to the gym).

Hitting the MagicFlip key causes the flap to spring open, revealing HDMI and USB 3 ports, as well as the crowning glory: an ultraast Thunderbolt connector. You don’t see many of those on Windows PCs.

According to Acer the Aspire S5 can boot from standby in less than 1.5 seconds, making it even faster than earlier UltraBooks. The Aspire S5 is expected to launch in the middle of 2012.

Acer has bought right into the Intel UltraBook idea. It already has a retail model – the Acer Aspire S3 Ultrabook – and used CES to announce the S5 and two other models: the Aspire Timeline Ultra, which comes in 14in and 15in chassis. Acer says they will have the latest Intel Core i chips, and be 20mm thick at their thinnest points. It is claiming a battery life in excess of eight hours, but they won’t have Thunderbird ports. Expect the Timeline Ultra laptops to launch in the next few weeks.
