Actually it had, I never knew that sort of things had existed. It is ok 
though, worse ideas have been implemented. Usability is a whole topic on 
its own but keep in mind that "usability" can mean different things for 
different people.

If a person with shaky hands is operating a computer _only_ selecting 
menus with space, bksp and enter, then sure I'm with you all the way; If 
he/she need to type on any of the 50+ other keys on the keyboard then I 
take it that it doesn't matter _how_ you design your software the 
"usability" is going to be bad either way unless you make all the keys 
to scale of course but that would look silly wouldn't it (although 
perhaps "usable" for that person).

"look like Windows" in this case is, believe it or not, actually a good 
thing [in this case].
