I prefer email over text messaging as the keyboard is much larger and I can get my d__n fingers on the letters.
My son and has his email forwarded to his phone so one day he called me and said, "Mom, if you don't like text messaging, just email me and I will get it on my phone the same way." Yikes, wish he had told me sooner. But in a pinch and on the run, text messaging can take care of a quickie conversation that a phone conversation isn't needed. My husband is in meetings a lot and I never know when I can call him, so I just text him.
