When more and more gadgets went from AA & AAA batteries to rechargeable non-replaceable ones, I thought my days of frustration and yelling were over. That wasn’t the case, though, since plenty of wireless mice and other gadgets still use replaceable batteries to power themselves. Besides having to go out and buy the darn things, putting the batteries in correctly when the device doesn’t do a good job of explaining how is a major frustration. Microsoft’s new “Instaload” tech hopes to eliminate that, with “allows users to easily install a battery without regard to positive and negative polarity.” Wow, it’s idiot-proof! Welcome to the future, folks. No word yet on when it’s arriving, but companies like Duracell are utilizing it, so it should be big, real soon.
