You've already seen a plethora of comments slamming the idea of an expensive smartwatch (or in some cases slamming the idea of a wristwatch entirely). I'm a huge Smartwatch fan -- I spend virtually all my day in meetings, often not being able to use my laptop (tells you all you need to know about my job, I suppose). I was using a Pebble for years before my spouse got me an LG G Watch. Then a year later my spouse got me an Olio and as soon as I verified that it couldn't make it more than about 10 hours without needing recharging, I returned it.
When I got the LG G Watch, I made peace with the idea of charging my watch every day, which felt a bit blasphemous to begin with, but ... no big deal. I already charge my phone every day (though it's a bit annoying that there are practically no standardized Smartwatch charging standards). I just needed it to last until I go to bed at night, which is where the Olio failed.
These days, I'm using a big, chunky, Huawei Watch (http://www.gethuawei.com/huawei-watch) which I like quite a bit and makes it to bedtime with about 60% charge remaining.
So why not the Apple Watch? Simple -- I'm more interested in continuing to use my Android phone than I am using the Apple Watch. Apple, in an attempt to create a vertically integrated stack and bolster up the iPhone (or maybe just because they're lazy), has made their watch only work with the iPhone.
