Google plays with "First Sale Doctrine"

Interesting

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."

I do not think this is going to stand the test of law
