And that's the sole reason I would want a watch. Definitely not to tell the time.
Also, I'm not sure that I consider cell phones to be disposable. At least not until it's time for a new one. A cell phone is so much to me. I never use it to call people, ironically(?), but it's a computer in my hand that allows me to easily communicate with people, and that's what I use it for, all day. More often than not, I'm on my phone. When I'm at home, and you see me on this site, very rarely is it on an actual computer/laptop.
