I carry mine everywhere and its not in a case. I just carry it in my hand. I really need to get one tho. Just not sure yet which one to go with.
I open mine up and read it everywhere possible. Its amazing how getting stopped by a train used to bother me. Not so much anymore.
I have yet to see anyone else reading with one. I just can't imagine not having it. I swear if it broke today I would be scraping up money from somewhere to run out and buy another one. Actually, last night I picked it up off the cabinet that I keep it on and as I was walking to my chair it slipped out of my hand. I thought I was going to have a heart attack! Well, it just kind of slid down my body and I caught it before it hit the ground. Made me realize even more that I need to get a case.
