I hate those places with a passion, and as a deaf guy I constantly get people just leaving me without any help after I mention for the third time to speak the fuck up. I wish I had an Apple store here, maybe buying things in a store would be more enjoyable :(
An Apple Store in New Zealand (and possibly other places) would do wonders for the brand - I only switched to Mac after a visit to the US. The next-best-thing we had in Auckland was MagnumMac - it was OK but it was no Apple Store.
Now, it doesn't seem to matter when I go to the Apple stores around me, they're buzzing with tons of activity.
Also, being close to an Apple Store helps other stores as well. I've seen so many parents just leave their kids at the Apple store while they run off to Victoria's Secret or BB&W. That section of the mall is completely busy when before it was just foot traffic going to Macy's or another anchor store.
It's not a condition though. My local Microcenter sells Apple laptops (always have) and have a little section for them, but it's not run by Apple. It looks like the rest of the store, and isn't laid out like an Apple store.
I've bought a laptop from Microcenter, and boy was it something I regretted ...
