OK I respect your spirit for the issue, but what store are you near? The store near my house has practically all of those things. There is a Garage Band setup - keyboard and all. There is a pro station with a vidcam plugged in - there is an iPhoto station with a Camera plugged in. Every iApp has a setup with related gear. Granted, there isnt an instruction sheet next to the screen, but are they that hard to figure out?

Hell, my 4 year old walks right up to the kids section and sits in front of an eMac and within seconds he has launched Tony Hawk Pro Skater.
