so i upgraded to 2.0 finally, and i have noticed that my battery life sucks when im gettin into apps and games on the go. beatmaker drains my battery so i tried to think of a solution. well here it is. i went to sharper image because of the whole "going out of business sale" thing, and got one of these for 7 dollars. they just use AA batteries and give my ipod the boost i need for those long trips.
