The last time we bumped into MSI's 15.6-inch X-Slim X600 we were unimpressed with the build quality -- it just seemed like too much plastic in too thin of a form factor to be trusted. Well, the X-Slim X600 Pro seems to have addressed some of the perceived quality issues, with a new scratch-resistant surface and silver inlays, but we'll have to play with one before we really know if these refinements are merely skin deep. The largest hardware tweak is the new chiclet keyboard, while inside the laptop has scored "the latest" Intel Core 2 Duo CULV processor, matched with the same ATI Mobility Radeon HD 4330 graphics from last time. There's no word on price or availability, but we're sure we'll be seeing and hearing more at CES.
