I purchased a HP Touchpad Demo unit from Radioshack. Since then, Radioshack has changed their policy and won't allow sales of the HP Touchpad Demos, even though some stores still have some. However, I have recently learned that HP replenished enough non-Demo HP Touchpads to Radioshack to cover the number of Demo units sold, so that customers can return to the store with the Demo's/receipts, and initiate the process to trade them out. I did that friday (9/2), and am currently awaiting my real HP Touchpad to arrive, so that I can swap mine out. I'll keep you updated.
