When I plug in my iPod Touch, iTunes gives a breakdown of what's on it - Audio, Video, Photos and Other. What is 'Other' because I've got 4GB of it. That's pretty much the same size as the photos I've got on there, so surely it's not just the OS, email and contacts/calendar? And is this normal? Luckily I've got the 32GB model - I'd be pissed off if I'd bought the 8 or 16GB only to find 4GB taken up by the OS and e-mail.
Cheers,
Will
