When the phone industry runs out of innovation, they bring back old tech like flip phones. What next? Physical buttons/keyboards? How about longer battery life? Oh wait, that requires real innovation, time, and money.
@nixCraft I've read (but not sure if it's true) that there is a EU regulation that makes it complicated / expensive to import/sell phones with more than 6000mAh of batteries. That's why that is currently the cap for a lot of asian manufactures. Some even put different batteries in phones in asia than for europe.
