Re: Your top changes? Words on Glass
Yeah, I don't think I'll stop using my keyboard for the majority of my typing, But I write articles for a living, so I'm not representative of everyone. Outside of knowledge workers, I can see touchscreens taking the bigger share.
For a lot of people, typing involves sending emails and text messages, making comments online, etc. I know more than a few professionals whose daily routine involves more communication through a phone or tablet than through a keyboard. Most of their communications are fairly terse, I'll grant you-- but the point remains. And if we include kids (who probably send 10 text messages for every sentence they type on a PC), the ratios will get even more touch-centric.
Moreover, modes of communication that are more conducive to touchscreens (e.g. Twitter is a start with its character limits, visually-oriented tools offer other potential) will continue to develop.
Does that mean keyboards will become unnecessary? No, of course not. But I won't be surprised if more words are typed on glass than on keyboards within the next five or so years.
