One thing I like about using the Pre, is the ability to look at the file structure when you attach it to a computer with a USB cable, and also on the device itself by using a program like InternalzPro. I attached my wife's iPhone to a PC and it appeared that you cannot look at (and play with) the file/directory structure. Are there any other mobile OS's/devices that allow you to see this kind of detail and ability to modify file locations, directory names, etc?
