The drive to work is dead time. There's nothing *else* you can do. You can't read the paper, for instance. And catching up on the news only takes a few minutes of talk radio. The traffic is better on the cellphone anyway, than from the radio. And, your navigation needs aren't all that great on a commute.
So, what you do is "conduct business".
Many people conduct business on the phone. So, that's what "I" do.
I almost never use the phone's keyboard to type anything, since Android has a decent speech-to-text translator. I wish I could get Android to
*default* to speech-to-text, because I find that I have to hit a tiny microphone at the bottom of the keyboard in order to put it into speech-to-text mode.I don't like audio books, but I can see that it's useful for whiling away the time while commuting.
I use the phone for business use. There are LOTS of people I need to talk to because I am a program manager. I don't actually do anything; the people I talk to do all the work. I just nag them to death on the phone. :)
