We saw another fun anecdote illustrating what happens here on HN recently. It was an unnamed MS engineer who explained the issue with post-Win7 design at microsoft was, that even though the actual programmer engineers _building_ it knew which way north was, the design struck out for them was dictated by Designers who themselves would only ever touch Macs (if touch any computer at all, not to smirch their design genius), and not lower themselves to consider how LEGACY WINDOWS (ie windows from 6 months prior) actually worked - which would anyway be IRRELEVANT, as they were responsible for designing the FUTURE, and you don't do that by looking at the PAST. And this is how we end up with the world's most succesful desktop OS having "Title menu bars that can no longer be used to drag the window", menu-bars consisting of ALLCAPS to hint it might possibly be a menu, a start-menu that you can no longer browse, where your installed programs never show up or disapppear, and where central OS windows no longer follow basic UI guidelines (goodbye incremental-keyboard-search, and the ability to sort and resize list columns), and hello scrolling lists without scrollbars, and goodbye indicator of how big this scrolling list is, and whether there are further items below to scroll into view. It is telling that Microsoft has not been able to produce a viable GUI framework/toolkit since 2006. Interestingly, WPF still sports 'the worst folder picker in the world', even though Forms has offered an excellent and superior folder-picker for around 20-22 years by now.
