Smell Machine at Sony Store

Even without spotting the SmellMaster 3000 at the edge of the Sony Style store's entrance, it was pretty obvious. The toaster-sized machine was pumping out cinnamon, presumably an odor that would attract passersby in the giant mall to come into the store. Well, at least it would make the store seem cozy and homey after you came in the door. Exactly how do you match up a technology store with the appropriate odor? What goes with computers, DVD players, camcorders and DVD movies? If you were selling baked goods, bedspreads or even sporting goods, I could think up a few smells that you might want to pump into your store. But techno? I have no clue what smell to use.
