funniest thing is that folks said the same thing about WinXP vs Win7 when Win7 came out.
Do you know that WinXP was released with over 5000 known bugs? Windows 2000 users were not overly anxious to move over to it when WinXP came out.
I jumped on Windows 2000 when it came out. Worked fine for me.
I bought Windows XP on the day it was released. Worked fine for me.
I installed Windows Vista from beta on4ward. Neva had a problem with it.
Windows 7 was on my system as soon as I could get my hands on it. Worked like a champ.
Installed Windows 8 only so I could upgrade it to Windows 8.1. Hated Metro, but with a little configuring it worked without grief.
Did a virgin install of Windows 10 pro and haven't found a single issue with it so far - at least no more hassle than any other version of Windows I have used.
Whether you upgrade or not is up to you. I am an early adopter because I usually like to be ahead of the game when quirks show up so I can find creative ways around them.
So far I have not had any hate for with any of these releases except Windows 8.0. But that is only for as its UI. Later versions of Windows and 3rd party utilities don't force me into that crap so I am happy.
