The first buyers of Google Glass are starting to get the smartglasses in the mail, letting them shoot hands-free video, pull up GPS directions in the corner of their eye and even hold video chats with their friends while they walk.
But they won't be allowed to let anyone else enjoy the device and its features.
In its terms of service for the early "Explorer Edition" of the device, Google says it has the right to deactivate any device if it has been sold or lent to someone else.
"You may not resell, loan, transfer, or give your device to any other person," the terms posted online say. "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."
Google says that these terms are specifically for the early version of Glass, so they may change by the time the device goes on sale to the general public. But for now, Google says it simply wants the first users to use the device, not anyone else.
