I noticed when I remove the battery to recharge it, that I have lost the date, time. Today I took some photos without updating the date/time and found that I could not resize the images. I then entered the date/time; took another photo, and this one was able to be resized! Quite a little quirk that I wouldn't have expected. I'm definitely ordering a couple more batteries, so that I'll have a charged one to put right in, while charging one, hoping this will eliminate having to re-enter the date/time info.
Just thought this was interesting.
