ooh my goodness... my battery died half way through the lecture I just sat through, and after no longer having it in front of me, and yes i actually was taking notes on the lecture, but I just sat there with walter in my lap or in my arms, and i just became bored to tears... but the good news is my battery lasted nearly three hours before it went kaput, so thats cool! Arnie only went an hour and a half before dying, so three hours is good... but I need to remember to put in the spare bttery I purchased and charge it/discharge it *and remember to carry it with me*
