Dell may be looking to reboot it’s screen-flipping netbook in Ultrabook form. The Inspiron Duo was a netbook offering from Dell which featured interesting convertible mechanics, wherein the screen flips around right inside of the bezel, allowing the device to function as a standard clamshell or tablet device. The netbook version of this didn’t sell very well, but the convertible concept might not have died with it. With Windows 8’s vastly improved touch functionality just around the corner, we’d love to see the XPS 12 from Dell.
