Quite.
One of the things that, over the years,I found to be both pretty good and disastrously bad, was (I don't remember exactly what they called it) .... adaptive menus. The things that changed and moved around depending on what you'd done recently. I mean, in theory, putting the things you use regularly towards the top of menus .... good idea, right? Not if you're like my wife, because the option might have been third down on 'this' menu yesyerday or last week, but it isn't today. It drove her nuts. Guess who had to suss out how to disable it.
I think MS underestimates just how many users, in modern offices, use a PC (usually a Win PC) as a tool. What they're really running is accounting software, WP, stock control systems, that kind of stuff. It's like a mechanic having to buy a new set of sockets and spanners every two or three years because car manufacturers kept coming up with new sizes and shapes for nuts and bolts. I mean, having Whitworth, Imperial and metric in my tool kits was enough of a pain. Usersjust want to do heir work and most don't give a left0handed flying fig where the print menu is as long as the damn thing stays put, and as for rounded corners ....
Okay, I'll concede the corner-shape thing is me being a smidge picky, and it makes no real difference to users (but,
IMHO, rounded look a bit nicer), but the point remains .... let users select the Classic style, if they want. If 3rd party utility house can do it, MS sure could.
