While this particular watch might not seem to be great in terms of ergonomics, i do think the reviewer did seem to miss the point of these "smartwatches". The Pebble , which is basically being released about now too, is the same thing and one of the main reasons these things are getting popular is not because we are too "lazy" to pull out our phones.
Phones like the Samsung Note 2 and even S3 are pretty large phones. Alot of us actually do use these phones for music, GPS tracking and all kinds of things while we are busy driving,running or working. Trust me, pulling out a phone in your pocket, the size of the Note II , only to change the song while driving, is a disaster waiting to happen. I listen to audiobooks while driving and often have to pause or play (or rewind) while driving, not a great experience if you don't have some sort of bluetooth interface on your steering wheel.
I cycle with my phone in my backpack, inside a waterproof bag....need i say more why a watch with the ability to interact with my tablet sized phone is actually quite a useful thing to have? (and thus not us being "lazy" or "facebook obsessed" ).
So yea, while sitting in a meeting and screening phone calls via my watch sounds more professional than constantly fiddling with your phone , there's a ton more to this than people think.
Personally, i'd still probably only go for this type of device when it actually runs an OS (i.e. Android or iOS) and can literally "remote" into your phone via Apps. Therefore allowing interaction with the phone without the watch itself being a phone.
I'm sure we're not far off from that, i've already seen Apple doing it with the iPod Nano (the square one) with a wristband accessory and an app that simply shows analog time. Again, ergonomics of that setup isn't too appealing and it's not as waterproof/outdoor proof as a normal watch. Battery life and all that also becomes an issue. No one wants a watch that needs to be charged every day either.
