With one small device I carry with me a camera, video camera, all my e-mails, GPS, sound recorder, note pad, flashlight and phone. Texting is an awesome way to communicate too. They have apps available to do a whole bunch of other things also. Maps, I always have a map with me. I used to think all these were unnecessary too but after having one for a while I won’t go back.
I bet it has a clock too.
I’ll think about it ... my Garmin GPS IS a little bulky
