Alright, so I'm new to my iPod touch (and Apple products in general). The Touch runs something like a computer would, so does it act like a computer in that each time you open/close an application there are residual files that remain open, that canwind up slowing it down? I don't know much about this, if it even applies to Mac computers/OSX, but I have been told this can happen in Windows. I would think something like this could happen to the iPod touch because there aren't any system tools for disk cleanup/etc (I'm still on Windows terminology, bear with me here, I don't even know if you have to do things like that on a mac). Any input on keeping my iPod Touch running fresh and smooth? Thanks!
