This is the smartest option these days. That way one doesn't have to constantly take out and put in batteries if the device is forgotten for a little while because of yet another new toy!

(Emphasis mine.) I feel personally attacked here. As I sit with a stack of Sharp pockets next to me.

I installed a diode in one of my 1211s as suggested by blackjetrock, and the screen contrast looks a lot better now. I always wondered why it seemed so dark... But strangely, my other 1211 seems to have rather high standby current. I noticed that the batteries in it were already down to ~1.25V, and putting a diode in that one dropped the voltage enough that the screen was very dim. Might just leave that one without for now...
