No, it is NOT mere opinion.
There is a science to developing effective user interfaces, that Microsoft brushed aside.
Conveyance is one of those factors: A good OS UI would convey, to the user, how to do certain common or important tasks. Windows 8 fails to deliver as much conveyance as most of its predecessors (Win95 and up), on objective grounds.
I thought your defense of that opinion was pretty weak.
Yeah, soooo weak that Microsoft now recognizes that it needs to backtrack on what they did, to be more in line with what I was saying.
Whiny and nitpicky might be a better description.
Small, nitpicky, things can make a HUGE difference in the usability of a UI.
The nature of UI design is one of practical psychology, in which many of its factors can be very subtle.
Could you imagine if MiCrOsOfT dEcIdEd To UsE aLtErNaTiNg CaSe in its user interface? It would drive people nuts, but any criticism of it could be met with "you're just being nitpicky!" Yet, there were a few games that almost did that, at least.
Could you imagine if the text in the title bars were only a few shades different from the background color? It would be really hard to read, but any criticism could be met with "Oh, get over it! It's just their choice of colors!"
Like I said in several threads, it was not dissimilar to the criticisms of XP I read when it was first released.
It's not my fault other people don't know what they're talking about. I, for one, was NOT one of the folks who criticized XP's UI. I thought it was all right.
I heard more criticism about The Ribbon in Microsoft Office, but you never heard me complaining about that, either, because it was a genuine improvement, on objective grounds. (Though, it would have been nice to have the option of a legacy menu bar, in the 2007 edition.)
I complain about Win8 because it is NOT an improvement. A LOT of FORCED change, for no benefit; and quite a few detrimental effects for those on KVM hardware.
Start Button? Who needs it?
As a matter of conveyance, it is needed. For those who can't swipe the edges of their screen, it's needed. For older users it would be nice to have. For IT personnel, it's a one-stop-shop for all the advanced features and applications and settings they need. Etc.
Just because you don't need it, doesn't mean other people don't.
People who found the transition overwhelmingly confusing weren't trying very hard. All the needed information was easily available.
Why should there be any effort needed at all? Why would they have to find needed information? Why can't the OS just work the way its users expect, right out of the box?
