With Glass, call handling has never been easier. The large 8.9" touch screen and the engaging user interface let you see everything graphically while on call. Like putting a call on hold, or taking it off. If another call comes in, you can see the caller and decide to take the call now or not. Switching between the two calls, and conferencing calls together is now a breeze. No more looking up phone numbers to transfer the call; you can transfer straight from your list of contacts on the phone.
