It's hardly an issue. For the same price of taking the train to downtown I can go to soho or the 5th ave store. Now for people out in the suburbs or country, location and proximity is far more important.
We're not saying it's an issue, we understand our city already has 4 Apple stores. And as for "for the same price of getting Downtown, I could go to SoHo..." Everyone doesn't like to go into Manhattan for everything. Especially when it's flooded with tourist! (no offense to visitors )
But that's not the point. When Apple brings a store to Brooklyn all we're saying is that they are other places in the borough that's better (both visually and accessibility) than Williamsburg.
4 stores in our city already, nice. But we also have 8.4 Million people that live here. 4 just isn't enough! I love Apple and I'm from Brooklyn, I'm just dying for a store in my borough.
