An optical drive. A 15.6-inch screen. A discrete graphics processor instead of integrated graphics. This is an ultrabook?
Actually, this is a landmark: The Acer Aspire Timeline Ultra M3-581TG meets Intel's 21mm (0.83 inch) thickness limit for 14-inch and larger ultrabooks, but packs features found in few thin and light laptops—most notably, an Nvidia GeForce GT 640M graphics chip that marks the debut of Nvidia's new Kepler GPU architecture.
