It's going to be a long time before users prefer their mobile phones for typing letters to a full-sized (or almost full-sized) keyboard. And it will be a long time before users prefer to watch movies on cell phones. Sure, these can be overcome eventually by some kind of technology, but I think that eventually computers will be everywhere and you won't need a mobile phone except when backpacking or something like that.

Here is a saying that you can attribute to me and send it in to wherever you send immortal sayings to: "All technology is transitional."

I think that the idea of someone texting while walking down the street is fairly absurd, even though people do it. I used to read books while walking down the street, and that was absurd too.

The typical person walking down the street is at most listening to something, and I think that will continue to be typical for many decades. People who are driving cars already have computers with them and will get more.

Mobile phones are just a transitional technology.
