I don’t know too many gadget weenies who aren’t also caffeine freaks. Surfing a universe of ones and zeroes while pegging the meter on your central nervous system just feels…right. Now, for all you BlackBerry-tottin’ joe-junkies out there, there’s a way to never be more than a few clicks away from a bean shack. Greystripe offers Caffeine Finder, a BlackBerry app that displays location info and reviews of some 45,000 US coffee shops (a couple of them NOT Starbucks). For Berry owners with GPS service, it’ll even guide your crashin’ ass to the closest re-fueling station.
