Cafe.com snags Denny's Restaurants: The NetNearU reseller will immediately deploy hotspots at 40 restaurants; Denny's has 1,700 locations across the U.S. See, now, I can see the motivation for Denny's: they have booths, they're open 24 hours a day, they're near freeways, and business travelers already use them in the a.m., late at night, and for dinner on the road. Flipping open a laptop while waiting for your meal is a logical extension.
