I'm a texting guy too. For short, logistical type things, its great.
We have 3 active teens (well, my son is 20 but acts like a teen) that are often out and about. They text us when they are leaving/arriving at places, working late, plans change, status changes, etc etc.
No need to have a conversation about it, just FYI kinds of info getting communicated. If there are any issues, I then call them.
However, I still use complete sentences, punctuation, and appropriate caps when texting. I'm not a OMG U R GR8 kind of guy.
Don't have a MP3 player, mostly because I just don't listen to music as much as I used to. I have thought about getting one for the car to replace storing CDs in the car.
