'Overlooking'. I've been impressed with the responses until yours.
I've read 'the plethora of reviews on it'. And there are mixed reviews. Some people love them, some people don't.
Very few of them say they "don't work well". Most seem to think there isn't a business case built for it yet. No killer app. And this is probably true...from what I understand, the apps that can be released for it are pretty much forward facing iPhone glances and not full fledged applications YET.
Who knows. Even with the full development kit for this, we may still not get a killer app. And it may not be the form factor people want in a computer. Or it may be far too early for this form factor. I liked what I saw with the Moto 360, and I read a lot of negative reviews as well as a lot of positive ones. Given that I own an iPhone, it wouldn't work for me. Kinda wish it could just as an alternative. I haven't seen a killer app for this either, but I like it.
As a programmer that MOSTLY scratches my own needs these days (I had a software business where I designed new OS's for synthesizers and things like that at one point)...and mostly doing data collection in academic / psychological settings, I could see how I could use one of these in a very unintrusive way. I have a few IOS apps that I use solely for my own needs, and turns out to be the killer form factor for these that I couldn't do 10 years ago (considering porting these to Android as I'd love to be able to get cheap equipment that was great yesterday but is considered disposable today to have as standalone packages). Maybe the watch form factor even if it doesn't catch on with the general public would be great for specialized work.
But again, I am in no way overlooking anything. I'm looking for a reason that these may be useful and keeping an open mind. A lot of reviewers bank on the fact that a lot of people want to be talked out of something, or told that they made the right choice by going with another team in the first place. I am loyal to my Apple products as I have an investment in them and as a former musician, they make the tool that I use the most (heh! and I convinced Apple to buy it from a company quickly going bankrupt which saved the software). But all in all, it is disposable technology. If I had to get rid of it all and start over with someone else's products...I'm sure in a few years time, I'd probably be just as loyal to that platform as I've now based my workflow around it. That is the long way of saying that I don't give a fuck about fanboi antics on any side.
