That's far fewer than I would have expected.
I thought there'd at least be one for every major area per state. I live within reasonable driving distance to 4 Apple Stores and I was sure the one in the Somerset mall (Northwestern suburbs of Detroit) would have them. Not everyone who shops there has a lot of $$$ but it's where those who do go.
I did want to look at one in person (if they ever have them out in a case). I wouldn't want to reserve a one hour appt to see them with no intention of buying. Then again, I wonder if they pre-qualify people (like before a realtor will take you to multimillion dollar house)_?
