Re: Time for some truly revolutionary GUIs?
Also privacy. Unless you are standing behind me you can't see what I am writing with a keyboard and mouse. It would be hard to write a confidential letter (something that happens all the time round here in an open plan office) by for example talking, without everyone else hearing it. Unless of course it was drowned out by the noise of lots of other confidential letters being spoken/shouted.
As someone said above, a variety of inputs INCLUDING a keyboard and mouse, or voice/swipey touch screen, would be the thing to strive for. People can then choose whatever is appropriate for their use. Voice might be just what someone needs at home.
