Having been heavily involved with computers for close to 50 years already, experience tells me to stay away from any new versions of operating systems for at least 6 months, if not a year.
Eons ago, it seems, when I was a systems programmer at a small IBM 360 installation, my primary job was installing and maintaining each operating system release as well as patches. I was told never to install a new release until the .6 version (18.6, 19.6, etc) was out. That way, the bugs had been worked out and patched. In the Windows world, I wait until Service Pack 1 is out and 'settled down' before I even CONSIDER going to the new version of Windows.
In short, I don't want to be the 'guinea pig' for some not fully stable/not fully tested software. One of the things I've learned through the years is that 'make the date' is more important to managers than 'make it 100%'. As a result, perhaps testing has been less than 100% thorough, the end result being there will be multiple crashes as a result. Some oddball combination of 'this' and 'that' and 'those' together will surely pop up along the line and cause trouble. Shortened testing never got that far. So the customer has to 'pay the price' for being bleeding edge.
Perhaps the most significant of negatives of not going to a new release right away is software compatibility. I go back to the DOS 1.1 days on PCs, and as I was writing and marketing software, I had to test and sometimes modify my software to be compatible with each subsequent version of DOS. Along came Windows 286 and later Windows 386 and the number of issues to handle 'exploded' to say the least. By Windows 3.0, I was out of the software business. Always having a number of hard drives and computers available, I purchased a copy of Windows 95 after it had been out for about a year. It was still on floppy disks. About 30 or so, as I recall. I installed it on my 'test' computer and found that nearly all the software I had been using under DOS and Windows 3.0/3.1 wouldn't run. I took it off and restored Windows 3.0 on that computer.
Through the evolution of Windows releases, I've discovered every new release of Windows (except 95 to 98 - updates to 95 made it very close to 98 before it was released - and 98 to ME), one or more of my purchased software products would no longer load or run. In later versions of Windows, the 'compatibility mode' option would get me by, but not always. Too often, I wound up buying/upgrading to an updated software product. In some cases, I switched to a competitors product. I think I've had perhaps 8-10 competitors' word processing products on my computers through the years before I finally settled down to MS Word. But wait...there's more... Even MS Word versions (and the rest of the Office package) would neither load nor run on a later version of Windows! I think Microsoft will support each version of MS Office across a total of 3 versions of Windows before it is no longer supported. That's how they get you again...you get stuck buying a new version of Office, too!
Which brings me to another point. Of the software you've loaded on your computer, how much of THAT will run under Windows 10? Are the vendors anywhere near being Windows 10 compatible with -their- software? Even if you like xxx software and use it 99% of the day, if the vendor doesn't have a Windows 10 compatible version available, you may have no choice but to live without xxx software until they do! I think just about every online forum I frequent, from this one to perhaps 6-8 others (not all photography related), there's ALWAYS a fair number of those who hurried to upgrade to the newest version of Windows and found their software products won't work. Hey...even I got 'caught' when my version of Adobe Lightroom wouldn't run under Windows 7! Fortunately, the upgrade was readily available and the problem solved. Lightroom 'got me' again when I upgraded to a Canon 5Diii and it couldn't handle the RAW files from the 5Diii. Fortunately for me, the update was available and free. I think there were 4-5 similar threads on this forum when users have upgraded cameras and Lightroom or other comparable products wouldn't process the RAW files from their shiny new camera.
Bottom line? It's far easier to move to a new version of Windows once most of its' bugs have been worked out -AND- the majority of software vendors have updates or versions available that have also been 'customer debugged'.
. Macs are really good computers. I used to have an Apple I I E and then a Mac about 20 years ago.
