1. Integrate a  power pad/ power mat recharging station within the Surface, either as a fold-up extension/leaf, or a section of the margin area. A user is moving photos on the Surface, his battery gets low. A red aura forms at the visible surface area surrounding the device, with an indicator or flowing trail towards the charging pad. He then lays the device there to charge and continues with other projects. The device aura turns green when ready to use.
 
2. Utilize QR codes to take advantage of the visual reader… use this for iTag or RFID bonus items, coupons, redemption rebates, etc., from the Surface owner venues, such as bars. Another way to utilize the QR code is via a Kindle or Nook or other e-Ink device.
 
3. Create an affiliate marketing channel specific to retail items within proximity of the Surface (similar to Massive billboards in gaming apps). A convention center might use an affiliate CTA structure for galleries, retail stores, or services sold within a convention or conference.
