What do you mean a specific phone or vendor? The Pebble has been around for a long time and has no such allegiances.
And ugly? Have you seen the Steel? It's more handsome than the majority of watches I've owned.
Calendar alerts, live weather, caller ID, and text messages all have made me a fan of my Pebble. Try one for a couple of weeks - I'm pretty sure you'll become a convert. I'm sure it varies based on style, but I've discovered that I probably only respond to about 30-40% of text messages (some are ignored, others are received ends of conversations). The rest can be viewed on my watch without having to ever mess with the phone.
With a watch and a blue tooth head set soon enough the question will not longer be who needs a smartwatch, it will be who needs a smartphone - I think the mini-tablet will ultimately reign supreme and act as a hub for tiny peripherals. That's what I'm hoping for at least.
