I am going to be buying a 2nd generation iPod Touch soon and was wondering if the cases that are sold at a place like Target are any good. Does anyone have issues with cases that don't fit right? Is the 1st gen Touch the same size as the 2nd gen Touch? Or should I be looking for a case that is meant for the 2nd gen? Any brands sold at Target that anyone recommends? Any help is greatly appreciated. Thanks!
