I guess I’m now an old fart. I like my books and my music in hand. Especially music — I would need to have a cell phone AND a good signal AND continuing income to pay for it AND a reliable company at the other end, forever.
There is no need to be a continuing revenue stream to the entertainment industry subject to the three conditions you mention.
I do not own one of those damn internet accessible cell phones. I own a TracFone ($80 per YEAR versus that much per month) which I generally keep in the car in event of emergency unless I'm traveling on business. I'm not going to watch a ballgame or answer e-mail on an itty-bitty 1.5" screen. I have a $150 Kindle (one-time expense) where I can do it on a nice 7" screen when I am away from home as long as I think it is important enough to pull into a nearby McDonalds, Starbucks or thousands of other places offering free wi-fi.
