Hi, first of all I'm a huge Apple fan and will buy almost any product they make, but honestly as an owner of an Apple Watch, I can say it is simply an expensive watch that won't look good with your suit or dress.
Still if you can afford it why not have a smart watch specifically an apple watch if you already have an iPhone, you will be able to read Messages, iMessages, WhatsApp messages, app notifications without grabbing your phone, somehow it saves the phone battery by not lighting or vibrating every time you get a message, you can reply to those messages with an emoticon or a quick message generated by the system or record a voice message.
It will allow you to view and like Instagram, Facebook, Twitter posts, Shazam a song, change the track you're listening to while driving, browse amazon and ebay, make a viber call...
It has an activity tracker which reminds you when yo need to move in case you're mostly sitting for long hours.
And maybe the nicest thing is that you can use it as a remote control for your phone camera, so if your hand is not long enough to take a selfie with your friends, just place the phone somewhere and use the watch to check the frame and capture the photo.
Battery life is bad though, barely lasts for 12 hours, hope they will improve in future models.
