Dell is also joining the group of companies that will deliver Windows 8 computers with the XPS 12, XPS One 27 and Inspiron One 23 models. Further, Dell is offering Windows 8 as an option on its current XPS, Inspiron, Latitude, OptiPlex and Precision brands.

The XPS 12 is two devices in one: a laptop that easily becomes a fully-featured touch-powered tablet. The flip hinge touchscreen display easily transitions between laptop and tablet mode with a simple flip. When in tablet mode, the display completely covers the keyboard. The Full HD display provides 90 percent more pixels than a standard HD display.

The XPS One 27 All-in-One is designed for creative enthusiasts, featuring a high resolution display and performance graphics for multimedia creation and entertainment. The design features a 27-inch Wide Quad HD Display, which has 78 percent more pixels than a Full HD display, and an articulating stand that tilts the display to a 60-degree angle.

Dell is also updating its popular systems in time for the holidays. The XPS 13 has been updated with a new specification, including the Ivy Bridge chipset. The Inspiron One 23 All-in-One PC is now available with a touchscreen option.
