Vista was quite good if you ask me, BUT there were some really awkward usability issues at a very basic interface level, like huge icons with no text, strange layout inheritence logic when you changed it, etc. Windows 7 was only really a UI fix, but one that did wonders for its image, and showing once again that good user interaces are hugely important. Windows 8, although a necessary step, was a step backward for many in that regard (though there were as many advances that particularly power-users like me really appreciated, such as far better multi-display support)
Windows 7 was also a regression in some ways compared to Vista. Windows explorer, was significantly worse, IMO. Losing the ability to easily sort content regardless of which view you were in was absolutely horrible and wrecked my workflow when working with many files. 2-3 additional clicks may seem minor, but gets to be a huge time waste (and annoyance) when you are used to easily doing it (single click) multiple times in the span of a minute or so.
That said, it did make things less cumbersome for casual users. UAC being less intrusive, for instance.
