I think Swatch can be a little bit cheaper at their airport stores than outside. This is another product with little retailer variation within a country, and it can be less expensive in Switzerland. I don't know about independent electronics retailers at an airport.
I think Apple's European markup before tax does not vary much across countries.
I think there's no airside electronics store at ZRH, and the duty free does not seem to sell Apple.
If the OP is UK national, she still has free movement to cross to the airport mall:

Prices include taxes. CHF and USD are at parity right now.
