Acer’ first Ultrabook, the Acer Aspire S3-951, is now available in North American for $899 (MSRP). This Ultrabook powers on instantly, connects to the Web in seconds and provides up to 50 days of stand-by time, or 6 hours of continuous usage. Measuring just half-an-inch at its thinnest and weighing a mere 2.983 pounds, it’s as easy to carry as a magazine or file folder. Its overall dimensions are 12.59 inches by 8.52-inches by .51 to.68-inches. As slim and easy to carry as a magazine, it still includes an Intel Core i5 Processor, 20GB solid state drive, Intel® HD Graphics 3000, 320GB hard drive, 4GB of memory, and essential USB and HDMI ports.
