HI all, I have a 256mb usb flash drive that's starting to get cramped so I'm thinking about getting a 1gb shuffle to get more space and a music player too. But first: I heard you have to allocate music space and file storage space beforehand in iTunes. Suppose I decided to use half for music and half for storage. Later I realize I need another hundred meg for file storage. Can I delete some music files to get more space? Is this possible on the larger ipods also?? Then related to this, if I format the shuffle with fat32, can I then use it for storage for both macs and pcs? I need the flash storage for both PC and Mac, but I'll only be using itunes on mac to actually load music on the device. Last, a side question: are there any other music players besides the ipod that can play AAC?? (not itunes protected of course) Thanks in advance.
