What use is it you wonder???
Simple.
Every time they change this s**t it means people (and by people I mean large corporations) to retrain their staff.
Books and other media need to be rewriten to reflect the changes.
And of course it means anyone trying to make a compatible UI has to chase your changes.
No matter how non-sensical they are.
And of course corporations can't give it up because (all those con-sultants say so) the costs will be soooooo much higher than just bending over and taking it.
Biting the hand that feeds IT
