> The Apple watch has to be activated to show you the time, while the Pebble always shows the time.
If the display was always on, it would be distracting, especially in dark environments (movie theater, concert, night time in general).
> The Apple Pay integration is interesting, but that hasn’t really panned out as something people really want.
Apple Pay on the Apple Watch is the easiest and fastest method of payment I've used. Simply double-tap a button and hold your wrist next to the reader. It's even faster than Apple Pay on the iPhone (and I can't drop my Watch), which makes paying with a credit card feel as slow as writing a check.
If every retailer offered Apple Pay, I would use it every time. It's especially convenient if I happen to forget my wallet.
That said, I hope the Apple Watch will eventually track sleep. I haven't found a good replacement for sleep tracking since Wake Mate shut down.
