I like the e-tickets and I like the way CU did it.
I have had CU season tickets since 1998, and there have been at least two occasions in that time where I have left the house only to turn around saying to myself "crap, I left the tickets at home." It got to the point where I had to put the tickets in my car the day before the game to assure myself that I would not forget them.
Now, as long as I have my phone. that will never be an issue again. And CU made it easier than I thought. Links in an email to each ticket for each game, just click on the link and add to my iPhone wallet, and its there. I now have tickets for all the home games, AtM, parking for AtM, and the kickoff luncheon on my phone.
Plus it saves the cost and paper waste of printing all those tickets, mailing them out, and disposing of them after the game (they often lived in my pockets for a long time thereafter).
I don't know about transfer of the tickets, and I really don't care. I have always used my own tickets, so that's a non issue to me.
I'm sure that many will, as my nana used to say, "kvetch all night long" about it. But I love it. The rest of you, please proceed to kvetch, kvetch, kvetch.
