Most of Apple's engineering is in USA.
And it is reasonable for the products to cost a little bit more in Germany, for example, to pay for some extra costs distributed across a smaller market (e.g.: localisation).
You must be joking.
The whole European market is being distributed centralized from tax favourable countries like Ireland or Czech republic. All shipments worldwide are handled from China anyway.
Things like localization are non-issue as well, because of being handled already in China during production and packaging.
There is really no real reason for the prices to be so much higher here in Germany compared to US ever since (long before the dollar became stronger).
The greed to succeed, I suppose.
