I recently had to upgrade the software in my 1st gen nano because I upgraded iTunes to 7. Since then, I noticed that in stand-by mode (or whatever its called), all you have to do to play a song is press the power up/play button once. However, sometimes I have to press it twice. Those "sometimes" it will power up the nano but not start playing then I have to press play again to get it started. Anyone with the new version of software in their nano have to press play twice sometimes to get the song to play and other times it only takes one press? Also, was this a feature with the newest software upgrade? I didn't notice it powering up and playing with one button press before the upgrade. Dunno if this happens with the video iPods, but it does happen with my 1st gen nano as well as my wife's 1st gen nano.
