MSI is working on second generation Ultrabook which features a touchscreen and convertible functionality. The S20 is a convertible Ultrabook which uses a sliding design, much like the Asus Eee Pad Slider and long forgotten (and never sold) Samsung Slider 7. The MSI S20 is equipped with Windows 8 which Microsoft has retooled for touch input with the Metro interface (pictured above). The S20 is exciting because it will be one of the first touchscreen convertible Ultrabooks with both Ivy Bridge and Windows 8 — a combination that could actually represent a good touchscreen computing experience in the world of mainstream PCs for the first time. We tracked down preliminary details for the S20, step inside to have a look at this exciting sliding Ultrabook.
