I work a job where I am limited on the amount of times I take my phone out. Our bosses do not care if we take a phone call here and there, but if we have our phone out, we can get in trouble. The Sony Smartwatch solved my problem. Instead of taking my phone out every time i get a message or text, I just look at my wrist and I know why my phone is vibrating (text message, email, message, facebook, etc.)

Battery life: it lasted only 1 day the first charge, but it got longer after that. This is expected with new batteries.
Phone used with: Motorola DROID RAZR MAXX 4G Android Phone, Black 32GB (Verizon Wireless)
*UPDATE - 04-12-2012 - I'm on my third day and the battery shows just under half.

Ease of use: Simple. You never need to sync it with your phone as it does all updates over bluetooth automatically. All apps you install on the Smartwatch are installed using your Google Play App Market. Once you install a Smartwatch application on your phone, it magically appears next time you connect it to your phone.



Connection to phone: Pair it to your Android phone for the first time, download the app it asks you to install, and every time you turn both your Smartwatch and the phone's bluetooth, it connects. At this point, any new information automatically is synced (notifications, new Smartwatch applications, etc).
I have had no problems in my first week with broken connections it is pretty solid with remaining connected. I lost connection once when I walked around 40 feet away from my phone with the Smartwatch.

OK... now for some more information and an update on my experience.
The Smartwatch DOES have two bugs/flaws.
1. After a few weeks of use, I have noticed the media player control widget does not always play nice. It WAS playing nice at first. Then Sony updated the widget and a problem started. This might be because I'm using the Google Play Music app instead of the Sony music player; however, it should not matter. I've had a bluetooth car FM transmitter with play/pause/previous/next buttons. Those bluetooth controls had no problems. The media player controls sometimes stops working if you have switched between 2 media player programs (Play Music and Pandora Radio). This of course means I take by phone out of my pocket and fiddle around with it. As soon as I turn on the phone screen, the SmartWatch media controls start working again. I do not know what the problem is. A future update to the media player widget will probably fix it.
2. Turn off your Smartwatch if the battery gets to red! It will simply lose power and need to be plugged in for about minutes before you can turn it back on. I thought my Smartwatch died on me! It did not: its battery was simply drained to zero and it needed a couple minutes of juice. Is this a flaw? Maybe not... I say it is since it freaked me out and brought me to think my Smartwatch died.


In short, NO IT'S NOT PERFECT. Am I happy with it? YES! It works pretty good and it CAN be updated. The more people that get this thing, the more it will be updated and also the more apps will be created for it. Be sure to shop around for the best price!
