I've owned a Macbook for some time now, but haven't ever had a reason to visit their store. I have avoided going in due to the high levels of smug - not only from the employees, but also many of the patrons. There's a general "I'm better than you" feeling at places like this that you can also find at Prius dealerships and many parts of California.
The reason for my visit, was that I needed a software update that could not be downloaded. Why I thought I would be able to pick this up at a place that calls itself the "Genius Bar" is beyond me, but I digress.
The "genius" took a look at my laptop, and said that I needed to order the update directly from Apple HQ... and then proceeded to tell me that he had no less than three other customers neededing the same update on this lovely black Friday.
I then asked him if he understood the irony of a company who prides itself on having most of it's information in the cloud - but not being able to help that many poor suckers in one day due to their policy, while STILL having the nerve to call themselves geniuses...
So, my suggestion, would be that if you only have ONE software update that requires an actual disk to download, maybe have a few of those in each of your stores. The good news? I don't ever have to go back. Which kinda makes me feel like a genius.
