In what way?
You can edit (rename/re-tag/ update artwork) songs already on your iPod, remove songs, copy songs back to your pc.
Sorry for being a bit thick, but why would you want to do that?
Also is it easy to copy songs across which are already on itunes?
I am also guilty of the cardinal sin of actually downloading an album or bonus tracks from itunes - would I have to download via Amazon or the like??

You could always use both it you like downloading from iTunes.
You sometimes need to re-tag etc because the download site be it iTunes,Amazon or whatever doesn't always have the correct info or you want to tag the artwork to each individual track & not just the album.
It has to be said, I prefer Amazon or Play for downlaods because they're quite often cheaper & a higher bitrate.
