Every person has his/her own habit. We can accept that not every keyboard has the same design, they can have their own customized designs such as Apple's keyboard, but we do care that keyboards should not become a tool which violates human common sense and hence hinders the use of it.

I don't think they should be the same design either. In fact, I wish there was more experimentation.

By the way, your RSI org notes seem to be down? http://thespanishsite.com/public_html/org/ergo/rsi.html is a 404.

Fixed. Thanks.
