I suspect that most folks that post on this forum have a high degree of tech-saavy ... at least the ones that are getting heated up on this particular topic. So I'm gonna guess that most of us have watched someone else use a computer, surf the web, program their smartphones, etc. So I'm thinking that I'm not alone in the belief that most people don't know how to "properly" use a computer or any electronic device in general.
I'll explain. Assuming that I am using the Internet correctly, if I want to go to my G-mail account, I open Safari (click the icon in the dock), and type in "gma" into the URL bar and hit enter (note - Safari will have determined that I want gmail even though I didn't fully type it in). That's one mouse click and 4 key presses. If I'm lazy, I'll just use the bookmark and reduce my expenditure to just 2 mouse clicks.
My wife, on the other hand, uses Firefox and Hotmail. So when she wants to check her e-mail, she clicks the Firefox icon, and types "hotmail" into the Yahoo search bar and presses enter (at least she's not clicking the submit button). Then she'll click the hotmail link in the search results. That's two mouse clicks and 8 keyboard strokes. This is the WRONG way to do it.
It gets worse. Have you ever tried to help someone try to edit a file that they just saved? Perhaps a co-worker. So there you are, standing behind them watching them navigate Windows Explorer ... drilling down several folders and back up. Taking 3 minutes to find the file. When the RIGHT way to do this would be to go START>My Recent Documents.
I hate that and I'm guessing that most of us do to.
I've read some of those articles that Arn linked and I've thought about this too. Most people's mind don't work in the same way that ours do. The thing is that computers and OS's are designed by folks that think like we do. So the way we operate computers seem natural because the interface was designed by people like us.
Touch interfaces are not designed for people like us. It's designed for people like my wife (and dad, etc). That's why techies will feel cramped and confined. We'll long for our keyboards and line prompts, but everyone else will be flicking and pinching away.
In the end, maybe it's not such a bad thing to simplify the interface. I don't need to use up all of my brain memory on such trivial matters as the Quicken Cmd shortcut to bring up the Saved Transaction menu.
BTW, I have learned to be patient when dealing with other peoples computer use techniques, but if you are a hunt/peck typist, just stay away from me ... well at least develop your skill to a point where you can type faster than 25 wpm.
