Written on the cover of the iPod which Gopu got for me from the US was this statement:
Don't steal music
Apple is being very considerate - they are calling us `thieves' and not `pirates'!
I had no second thoughts in getting rid of the Apple firmware and instead loading Rockbox, a very capable GPL'd replacement firmware which lets you play lots of audio formats (including Vorbis). The UI doesn't look pretty - but it does the job - my wife is using it without any problems.
