I need to preface with I do not use my phone for work and I never have...
It took me a while to get a mobile phone. Most of my friends had them for years before I bought my first one. Once I had one I thought, why didn't I get one sooner. Once my kids started travel sports, texting was the norm for communication so I added the texting package to my flip phone sans qwerty key board. What a pain in the rear to type anything so I bought a phone with a qwerty key board and found I could get needed information from people much quicker with a text than a phone call. I thought I should have upgraded to to this qwerty phone and a texting package a lot sooner. When smart phones first started showing up I was a little hesitant but got in on it pretty quickly without any regrets. Among other things, I cannot tell you the number of times, or hours of sitting in traffic, my phone (GPS) has saved me from by taking a detour around traffic because of an accident, construction, etc. Navigating around real time traffic alone makes my smart phone more than worth it. When my kids are at practice, I routinely watch Netflix and surf the net. Could I survive without a smart phone? Of course I could, but it makes my life much, much easier.
