In 3-4 years the cycle will repeat again with Windows 12.
People don't like clearly unfinished products rushed to market before they're ready.
The only advantage I had over the majority is that it was a brand new computer (with 2GB of RAM, wow) so I did not experience slowdowns.
Vista was better than XP in every way except performance on the low-end.
Windows 8 was an exciting change from Microsoft, but yeah some things weren't fixed until 8.1 and the damage was done.
I do find the search function is snappier and more accurate though. If anything this is a return to windows 7. It is definitely not problematic like vista or 8.
Now better wait for Windows 12 until they make their mind what Windows desktop APIs are supposed to look like.
