I'm currently got a 16GB iPod Touch 3. I've only used up like 2GB but as soon as I'm bothered to download some more albums I'm pretty sure I'll fill that up in no time. It would be nice to have a little more space (I wouldn't mind 64GB) to fill em with more music, apps and videos without constantly worrying about my avaliable space. I can live with 8GB but when I previously had an 8GB iPod, I was forced to delete a lot of albums just to replace them with newer ones.
