I"m not seeing the point in this. My hubby has a fan beside the bed. If I want a fan, I'll just lay on the bed and have his fan blowing on me while I play a handheld.
Neat! I imagine people commuting in a country where central air is not common who have a lot of wait time would like this to pass the time (assuming they don't want to drain their mobile device's battery as they wait).
I feel the gaming handheld console will use very little battery life because its screen is non-color like a calculator and the games are retro games which can run on less powerful devices, and the screen does not have a back light, so the fan can probably keep blowing air for a very long time while the user play games which may help them deal with the heat while riding a bus or train with no air conditioning.
