I can check my bank account directly on my wrist.
And if you really want me to prove to you the convenience of having a apple watch, I will. I work in a biochemistry lab, and have to wear gloves. I am in contact with cancer cells that should not be taken lightly. Now, how inconvenient would it be if every time I wanted to check my phone, time, texts, calls, anything, to have to take my gloves off, go sanitize my hands, then finally be able to use my phone. It would be extremely inconvenient. HOWEVER, with an apple watch, that syncs directly up to my phone, I can start timers, check texts, have full access of Siri by just saying "hey Siri". I think I have proven my point. ;)
