European prices are tax included while US prices are given without state taxes. That would already be a 20% difference.
Where I live the Pixel 10 Pro is sold for 1099€. That's around 1281$ at current exchange rate. So, 1000$ in the USA, plus 20% taxes, you get a 81$ premium for currency risk.
Compare that to the iPhone 16 Pro: 1299€. That's a whooping 1432$ for a phone priced the same as a Pixel 10 Pro. Even accounting for taxes, Apple thinks you should pay an extra 232$ because, well Apple, why not gouge foreign customers on top of making a mockery of the law of their countries.
