I've been quite interested in smartwatches in general because I actually think they can be quite useful, depending on the implementation.
I haven't had the courage to get one yet since technically the current offerings seem to be a bit on the weak side, and they tend to look the equivalent of those calculator waches from the 80s.
The Motorola watch seems to be the first smartwatch to actually look the part, and hopefully the Android Wear thing will cover the other part. We'll see.
Anyway, I do not see the watch as redundant to my phone, but rather as an extension of my phone's screen.
Take the following scenarios where you'd typically be fetching your phone from your pocket or holding it in hand for a long time only to glance at it from time to time:
- Using walking directions
- Checking why the phone just vibrated (or if it vibrated)
- Controlling the music player and the volume
- Checking the time (ah!)
You don't need fancy hardware for any of that. You phone already does all those things, so all you need is a screen, battery, weak processor and basic input.
Look at the reverse situation: why would you want to watch a video on your phone if you have a huge flat-screen TV in front of you? Ideally, you'd make that TV an output to your phone and watch the video there - the kind of thing which is starting to be possible with devices like Chromecast, or those DLNA boxes.
