How much space do iTouch apps take up?

Eban C asked:


I am planning on getting an iTouch but am debating whether to get a 8gb one or 16gb. My question is how much do the iTouch apps take and would I have enough room on the 8gb one for music and movies?

Also another question is, I heard someone say that the iTouch software takes up 2 gb…Does that mean there is only 6gb left? Or was that person incorrect?
