Smartwatches
Other wearable tech I'm not so fussed with, but for a smartwatch, i want it to do a few key things, and not much else:
1) it has to tell the time.
2) the battery has to last a couple of days at least, if not a week.
3) i want to be able to pair it with my phone to display notifications.
4) It has to look like a decently-classy watch (not bling-tastic, and not too non-normal) and provide 'normal' functionality (i.e. decently waterproof to a sensible level - say 25m - so it can survive doing the washing up or not being taken off in the bath / shower)
That's it. Doesn't need to do more than that. I don't need to be able to make calls on it, or read messages, or use it as sat-nav, or anything like that. I want it effectively as a second-screen that will buzz when I get a message, as if my phone is in my pocket i often don't feel or hear it.
Nothing more, nothing less.
Dropping the level of functionality would help the battery life a lot i suspect. A quad-core Snapdragon 400 in a watch seems like total overkill!
Even the Pebble tries to do too much, and I'm not sure I like the look of it. The Qualcomm TOQ looks like the right kind of thing, but looks awful! Quite like the Asus Smartwatch, but they need some development and the battery life isn't great. Some of these new watches from LG and Huawei look the part, but have so much kit in them that they don't need really... LTE on a watch?!? What's the point if you (as everyone does) ALREADY HAVE A PHONE!!
Also - I saw an idea about batteries being put in the strap of the watch - either a flexible cell, or metal links with a small 50 mAh battery in each link that connect together. I'm amazed someone hasn't developed this further.
