I bought my first gen Touch the week they came out, back in October 2007 if I remember right. I've finally noticed the battery life is shortening the last couple of weeks - especially when I play processor intensive games like Tetris. Music still gives me hours, but Tetris reduces a charge life to about 45 minutes. I was just wondering what other 1st gen owner's experiences have been? Are your original batteries still going strong? Or have they already been replaced?
