Google Is Forbidding Users From Reselling, Loaning Glass Eyewear by David Kravets and Roberto Balwin 

"Google is barring anyone deemed worthy of a pair of its $1,500 Google Glass computer eyewear from selling or even loaning out the highly coveted gadget.
The company’s terms of service on the limited-edition wearable computer specifically states, “you may not resell, loan, transfer, or give your device to any other person. If you resell, loan, transfer, or give your device to any other person without Google’s authorization, Google reserves the right to deactivate the device, and neither you nor the unauthorized person using the device will be entitled to any refund, product support, or product warranty.”
Welcome to the New World, one in which companies are retaining control of their products even after consumers purchase them.
It was bound to happen. Strange as it may sound, you don’t actually own much of the software you buy today. You essentially rent it under strict end-user agreements that have withstood judicial scrutiny. Google appears to be among the first to apply such draconian rules to consumer electronics."
