Frankly, for all users, I think quality, no bugs, regressions etc are much more important things than a nice, "pretty and smooth streamlined" look, elegance...
It's an OS and a computer, not a game console or like... It's a tool which must be efficient, usable etc not necessarily "beautiful", but I'm probably not fashionable and probably from the "old school", is not it?
In fact, I am "grumpy, depressed and older than I would like to be."
I don't say it's absolutely a bad thing but focus us on that is perhaps a bit excessive, right? Again, nice or not I do not care a bit, if it works perfectly and as I like then I'm happy... Plus, anyway, I hate all these things like 3D desktop, widgets, effects...
Yes, I know, I am an "old" grumpy
