(short comment on non-educated users)
I think theme might be a need to ask what an uneducated user is. Someone
who realy is uneducated couldnt care less, since he or she should never
traverse anything other than ~ anyway; besides /media that is, but that
sort of user wouldnt ever know CDROMs mounted outside ~, or even
understand the concepts of 'mounting' or 'home' in the first place.
(back on topic)
The problem is only for above average windows users, and even then, I
wonder if the problem isnt more about unlearning and relearning than one
system being better than the other. (Mind you, i prefer the Unix
filesystem layout to the
throw-stuff-into-the-air-and-let-it-fall-as-it-may approach of Windows.)
Package managers makes this more or less a nonissue from the users
perspective anyway, as has already been said. Using a packagemanager to
manage- and browse your installed applications (much like the Windows
Add/Remove panel, btw) instead of a filemanager is realy just using
diffrent tools for doing the same thing, with packagemanagers being more
capable and powerfull than anything you can do by hand with a
I think the reason this isnt worked is that there is no pressing need
for such a change.
