Configuring iPod on Linux
I'm not sure about state now but Apple is know for play of cat and mouse. You may find one day that update of software of iPod had broken its compatibly with Linux by completly redesigning its format.
Until one day someone reverse engeneer the new format and supplied patches for projects. It lasts as long as Apple would not decide to switch format again.
In short: iPod is not the best player for Linux enthusiast but when you have it you may be able to use it.
PS. Also Banshee have iPod support
