Mostly about effectivity vs. efficiency in terms of game programming.
My NXT rechargable battery finally arrived. It's quite creepy how quickly one tries to finish his tests with it running on battery. I highly recommend buying one (nature will thank you). But it comes at a pricey level... Especially cause these fuckers force you to buy a cable AND a battery to get it work, making effectively 82€ for a rechargable battery. I bet this could've less and combined... Whatever.
