The Apple Watch isn’t just a watch, interchangeable like any other. It’s an entire mobile computing and communication platform, and a significant enhancement to the smartphone, which is probably the most successful, ubiquitous, and disruptive electronic device in history.
Once you’re accustomed to wearing one, going out for a night without your Apple Watch is going to feel like going out without your phone.
Yep, probably so.
