As you can probably tell when it comes to the latest and greatest technology I have it.
I'm currently carrying everything apple with the exception of the Microsoft surface on at&t 4g LTE network.
If you have an iphone 6 plus or 6s plus the apple watch is a must have. It is literally your sidekick and you don't need to pull oyur large phone out or carry it around to answer calls and text. This is huge if you work somewhere where phones are not allowed. Your emails as well as any other type of notification you get on your phone are pushed to your apple watch as well.
Where the apple watch fails is if you leave your phone at home. I am currently a store manager for Sprint and I have a sprint work phone and sometimes I forget my personal iphone at my house. The watch is useless without the phone.
With that said the 500 entry level apple watch sport is a great buy. I personally have received several calls via my watch and it was fast and convenient. I can honesty say as a person with many expensive watches I have found myself in the last few months wearing them maybe once or twice and when i don't wear my apple watch it is odd because I am so used to answering my notifications via my apple watch.
Must have apple watch apps are
Celero- twitter app
Unhand me- notifies you when someone touches your iphone
Amazon- notifies when packages shipped and delivered.
Knock- You can wake your macbook or imac from your watch.
Calbot- makers of tweetbot calculator app.
If you have At&t then take advantage of the great network and buy yourself an ipad pro.
If you purchase a lot of premium games like me then the screen size upgrade is worth it alone.
