Expanding its lineup of super-portable laptops, Acer rolled out another solid Ultrabook entry in the form of Acer Aspire S7 13.3-inch laptop. Windows 8 Pro-based, this device can be operated either via mouse and keyboard, or through a touchscreen. Acer Aspire S7 actually facilitates the touch operation by enabling the display to be opened 180 degrees and the view to be flipped with a single hotkey allowing you to share it with a friend sitting in front of you. It also comes with dual-torque hinges that keep the display stable when you control it with your fingers. Obviously, the laptop is housed in a super-thin, lightweight aluminum unibody that Ultrabooks are famous for. With its 4-cell batter, Acer Aspire S7 offers you a decent 8 hours of working time. $1279.99
