The major problem about this device is its battery life. Apple itself is promising 18 hours backup without the screen being always on, many, hence were wondering if it will be able to last you through a day of heavier usage. It has a thick frame and the price tag was expected to be better.
We'll have to see the new operating system developed from scratch is as cool as it's hyped up to be. The Watch App store, is still in its infancy, and will need to convince customers that it's worthy of a device thats quite expensive.
Poor battery life
Works only with an iPhone 5 or later
Screen isn't always on, relies on wrist turn gesture
No sleep tracking (though your watch will most probably be on its charger while you sleep)
It will only sync music with your phone when it's on a charger
Expensive and limited availability
Apple Watch gets many things right - it comes with a cool design available in two sizes, and you even get both S/M and M/L bands in the box. It integrates well with your iPhone and will certainly reduce the number of times you need to reach for your phone. Plus you get all those strap options, some of which are pretty innovative on their own.
The new Apple smartwatch platform is pretty easy to get used to and comes with more preinstalled apps than its rivals, enabling better out of the box functionality. Then you get the fitness tracking which is among the best you can get within a smartwatch.
The Apple Watch is for those who are already into the iPhone ecosystem and it looks like it will take some more efforts by Apple to turn smartwatches into its next big thing.
We appreciate many of the ideas that come with the new platform and the design of the Watch.
The answer to the question whether you should buy one is probably based on your desire for trying out Apple's latest than any practical reasons.
