Ah..., when human and machine become one...
Resistence is futile!
But seriously - look at the keyboard there. It's all about, "I want THIS." It makes sense in a particular way. The point to abstract away is simplicity and instant access.
Quite often I find that in order to perform a task, I can either fart around learning some wierd software, or I can just program my own. I end up programming my own utility very often because it's just easier for me. Computers *should* be easier than that!
Just look at what it takes to get anything working on a Linux box! Mother of god! There's no way a regular person can do that! Windows is bad enough, and Windows is "easy".
The key to computing is dumbing it down at first glance, but leaving more powerful options available in a way that novices can get things done NOW, while more experienced users can get complex tasks done also.
Why does the average user ever need to choose between Deflate and PPMd when they try to compress a file? That's just stupid. Nobody knows or cares what PPMd is. All they care about is that they can compress the file to a nice, small size. These kinds of things need to be available to power users, but hidden from people that won't understand what they are. The picture there shows this kind of task-oriented approach that a novice or "regular person" takes.
