so i;m getting the 2G touch soon (who isn't in this category) and with my 1G nano and ny other ipods i fall asleep listening to music. when i get my touch i want to have a great battery (who doesn't) so my question is: when i have low battery and charge it at night, is it ok to leave it on the charger all niht (midnight-6.30) with music playin while it charges? or will that hurt the battery? also how long should i charge it once i get it and do i put it on the charger right away or run the battery out and put it on? any other battery info will be great THANKS!!
