Rumors of an Acer ultrabook's imminent launch were, as it turns out, entirely founded. Earlier this morning, Acer lifted the curtain on its Aspire S-series ultrabook. There's a mini-site up over here, which reveals that Aspire S-series systems are just 13 mm (0.51") thick at their thinnest point, weigh less than 1.4 kg (3.1 lbs), and feature a "sleek and durable" magnesium-aluminum cover. There's also talk of a "fast processor, long battery life, SSD, optional HDD, [and] essential ports."
The guys at Engadget were able to snag more details. They say the 13.3" Aspire S3 packs ultra-low-voltage Core i3, i5, and i7 processors and "up to seven hours" of battery run time. European pricing will range from €799 to €1,199, presumably for different configurations. That works out to $1,139- $1,709, but a straight currency conversion is usually a poor indicator of likely U.S. pricing—for example, Apple's cheapest MacBook Air costs €949 in Germany and $999 in the States.
Whatever the exact price may be, Engadget says the Aspire S3 will be available in the United States later this month. Impatient souls can check out the site's hands-on preview here.
