I find Glance very useful already. Be it on the desk or during a conference, it allows to check the time without having to unlock the screen or impolitely lol at the watch. On the wireless stand it makes for a perfect clock or alarm-clock. With Gdr3 it will become invaluable, replacing a notification light and informing at a glance about missed calls and notifications. I often check the time with the phone, and it's just easier with Glance. It's not laziness, but convenience. You got electric light in your home and not candles right? I love glance, makes the phone easier and more practical to use. It's always on for my 920 and my GF's 620, no noticeable battery drain.
