What is your use case? You are asking for something like an iPod, but the screen is not important. When you look at an iPod touch, the main feature is the screen! I think you need to give a better description of what you are looking for. Is it a one-off project, or are you developing a product? If you want something like an iPod with a touch screen, look at android devices. Otherwise there are add-on boards for the raspberry pi that let you connect a battery.
