can you overcharge it? Or shorten the battery's life by charging when it's already full.
For ex. mine is half charged right now. I'll be gone for the weekend and was going to plug it in tonight till morning so it's fully charged for the weekend.
Does doing this on a semi-regular basis shorten the battery's life?
And I agree, it'll be a long time before I get used to disposable electronics where you can't replace the battery for something that is otherwise perfectly functional even if there is a superior successor.
Right now there is room for growth, but say you have a reader that does everything you can image and there's little inceptive for the next model. At that point, you should only buy a new one when your hardware breaks, not when it simply has a dead battery.
