Dell has been teasing its ultrathin Adamo XPS for weeks now, but all that goofing off will come to a solemn end next Thursday. On the same day that we sit down with Microsoft's CEO Steve Ballmer (and a little OS by the name of Windows 7 hits store shelves), Dell will also fully reveal the planet's slimmest laptop. The 0.39-inch Adamo XPS will cost $2,000, and while the nitty-gritty details are still under wraps, a new Business Week article notes that it'll boast a "heat-sensing strip on the lip that, when swiped with a finger, glows white and automatically opens the aluminum lid." The glamorous machine is part of a larger effort within the Round Rock powerhouse to revitalize itself and get people talking once again, and while this particular slab will obviously not be a high volume product, it could very well get a few more eyes pointed in its direction. Call us crazy, but we're guessing next week is going to be a wee bit zany.
