Don't go to your neighborhood Apple Store. Go to MacMedia instead!
These guys are great. Friendly. Knowledgeable. Very different from the salesy/corporate feel of the apple store. If you want a cool show, then go to Apple. If you want someone to give you immediate attention and solve your problem, go to MacMedia. Prices for hardware are cheaper. They have both Apple AND compatible hardware/devices. Maintenance is quick and friendly. Every time I have gone there, the price has been less than the original estimate.
And.... If you are on the West Side, you have to park and walk about a half a mile to get to Apple store inside of Arrowhead Mall. MacMedia is just a few blocks from there, and you can drive right up to their front door.
