Hardly a fortnight after Windows 8___s official launch, Acer has sent our way its very first Windows 8-ready ultrabook, the slim and beautiful Acer Aspire S7. It may well be the slimmest ultrabook around, and while we put it through its paces and work on the final review, here___s our first impression of the Acer Aspire S7. The unit we received for review sports an ultra-low voltage dual-core Intel Core i7-3517U 1.9-GHz processor, 4 GB of DDR3 RAM, 256 GB SSD (Default RAID 0), and onboard Intel HD 4000 graphics. It came with a portable wireless Bluetooth mouse, additional battery pack, and HDMI-to-VGA and USB-to-Ethernet connectivity cables
