Exterior of Apple store in suburban Dallas-Fort Worth

Packed on a Sunday afternoon. Notice the iPads sitting next to each display model.

The iPads are affixed to the display tables throughout the store.

Each iPad is connected to Apple's proprietary in-store information application where customers can learn more about products.

This is the screen displayed next to the MacBook.

If customers need help from an associate they can request it through the iPad. The customer is placed in a virtual queue and an alert goes to associates' handheld devices telling them where to go to help.
