I remember seeing a preview of win 8, shortly after it was announced, in an ad before any usable preview version was released.
It was a picture of --what I assumed at the time was-- the start menu...cluttering up a whole screen with an array of tiles.
I believe the ad said something along the lines of "windows 8 let's your apps show off their personality".
Now, I've had apps with "personality" before. Like the stationary program that, every time I clicked "close" would bring up an exception saying that it had "encountered an error" and needed to (guess what) ...CLOSE...
So no, MS, I don't want my apps showing off "personality"... I'd much rather have them function correctly, and be available in a simple, easy list format...even if said list doesn't exhibit a "personality".
Then MS released the preview version of win 8. It was even worse than it seemed in the ad...now the start menu was gone entirely, and the new "metro" UI was ostensibly designed for touchscreens, with little or no concern for it's usability without them.
Fortunately, there were options to disable "metro", but reluctance over the upcoming OS persisted among the internet community.
"Windows 8 is the new Vista" was a common view.
Finally, Win 8 was officially released, now with the user friendly options removed...
No disabling the metro UI... And why? Because more users had hated metro & turned it off than had been using it!
Rather than saying "ok people hate metro, maybe we should learn from that & get rid of it"
Microsoft said "ok people hate metro, let's take away that 'disable' option & force them to accept it"
i.e. "We are Microsoft. Your computer will adapt to service us. Resistance is futile. You will be assimilated".
Now people are somewhat split as to how windows 8 is doing. MS insists they're doing well, "just look how many licences we've sold"
Sure there are a lot of licenses sold, but most of those are on retail machines. Even if win 8 machines sell well, how many of those buyers are planning to "downgrade" to win 7, or install linux?
Some say it's not doing well, because software developers aren't making many apps for win 8. Obviously new programs have to "follow the money", so to speak; there's no use making apps for an OS few people are using & ignoring an OS many are using.
And an OS with no software isn't going to very popular.
But, in my opinion the numbers & financial statistics don't really make a difference.
To put it simply:
If your OS needs third party software to add an essential, & previously standard, feature (start menu) or just to make the UI generally usable; if the acceptance of your OS by users hinges on said programs....well then.....it's a fail
