It's a drag that products like Windows are stuck forever the way they are. Or, rather, that they're stuck the way they are but then command such market share that nothing new ever comes and sees the light of day. Windows is doomed to keep generating billions for Microsoft until one day it doesn't, which I guess is what they're going for.

It also seems silly to tie the decline of Windows to UI discontent. Windows is in decline because it's increasingly irrelevant in the post-PC, post-USA world, and sucks in general.
