Warning: Don't buy an European iPod, it's volume is too low
The NEW iPods do have the volume cap that was introduced in the iPod firmware back to version 1.2.x already built into them. But Apple seems to have overdone it: the European iPod's max-volume is so low, that you can't use your iPod in crowded places like a subway or bus. You simply can't hear the music at an efficient level! According to user's tests the volume is about 25-30% lower then with the US version.

But not only the headphone jack is capped, also the line out: That means, that if you connect your iPod to a stereo at home or in the car, you have to turn the volume of that stereo way up what in many cases is causing sound-distortions.

Oh great, so the whole of Europe suffers just 'cos the French don't like ze loud muzeek.

Typical, spoiling everyone else's fun as usual. :(

thats why I decided to import one I commute and the louder volume comes in handy on noisy trains/tubes

Fortunately I got mine a couple of years ago, so it is unadulterated (unlike my ears, must be all that loud music :D )
