Battery life has improved radically since the phone first came out. Back then, the reviews were rightly complaining about 18 hours then a dead battery. These days, with the latest 5.0 firmware, After 18 hours the battery is still ~2/3 full. It's really amazing what a lot of dedicated software engineering can do for battery life.

The thing that really sold me on the watch, never mind my personal watchface hacking, was when my phone rang. I looked at the watch and it was somebody I just wanted to send straight to voicemail. And I did it with a single swipe, never touching my actual phone. When that happened, it was one of those "wow, the future" kinds of moments.
