In the middle of Tokyo I see a lot of laptops in Starbucks but that isn't really the case in most of the cafes I visit elsewhere. Not a great idea to extrapolate from a metropolis of 20 million to an entire country. If laptops are doing so great in Japan why is Sony selling off their VAIO business?
