The Treadmill of Notifications
My watch buzzes: "You've received a notification!" Great! What is it?! I look at my watch. "Notification from: Phone." THANKS. VERY HELPFUL.
It also tracks my steps, which reminds me I haven't moved enough. Now I feel guilty AND lazy. Thanks, technology!
The Battery
I charge my watch more than I charge anything else. It's like having a second phone strapped to my wrist. The future is exhausting.
