I agree with you. As a minimum, they could change the icon descriptions, pop ups etc. Ie, just because I have a credit card resisted in the Netherlands, it shows "Mandje" for "Shopping cart" and "OK/Annuleren" for "OK/Cancel" and this has nothing to do with the store that you looking at. If I change store to one in the UK, I can reserve a device whose description is in English and prices in GBP but all of the interface language is in Dutch, just because my credit card is registered in the Netherlands.
This appears to be some kind of bloody mindedness on Apples side. For example, the MAC App store application used to give you your menu options in the machine language - that was "upgraded" so you could only get them in your credit card language. These are menu items, nothing to do with TAX or Legal requirements.
The Dutch iTunes site used to be in English, then it was in English and Dutch and now just in Dutch. The ironic thing is that most of the songs and applications are described in English but the whole UI is in Dutch and all of the apple descriprions of their own software is in Dutch.
Hardly anyone in the world speaks Dutch
There are over 100,000 English speaking people in Amsterdam
Most of the TV is in English (with Dutch sub titles)
I can go into almost any store (be it physical or on the internet) and speak with someone in English
Why is it that apple cannot even give provide menu options in the language that the CUSTOMER wants.
I am sure that when the Apple people came over here to set up shop and sign contracts, they spoke English with their Dutch counterparts.
