I see the development as well. I hate Windows 10 as much as the latest Mac OS. I used to have a windows 7 pc until last year when i upgraded my studio to mac. Actually i am really obsessed by mac now although i had to downgrade to mavericks again (works far better for me than the latest OS). The only negative side is the slower CPU power compared to the windows pc if you want to spend the same amount of money. If i stayed with Windows i'd rather not update to Windows 10. Again workflow and everything...
We're a Mac household. There, I said it. A Core2Duo mini lives under the TV and does all of the streaming and DVR stuff (and it's also my Subversion server!). I have an Early 2008 Core2Duo iMac with a second monitor as my main workstation, where I do electronics design (Kicad, ARM with Eclipse, SiLabs 8051 with their tools, and [ugh] Xilinx in a WinXP VM) and digital audio stuff (Logic, I do not do ProTools). I have a 17" quad Core i7 MacBook Pro (last of the breed). My wife has a quad Core i7 mini at home and another one at her office, and she just got a new 13" MacBook Pro.
So, that said: all of the machines get upgraded to the latest OS a few weeks after it goes gold. (the exception is the mini under the TV.) The only trouble I've ever had with an OS upgrade was when I tried to update the iMac to 10.10 (Yosemite). The machine came to a crawl. There was something going on that it didn't like and I couldn't figure out. My best guess was the Drobo software (which sucks), and after a few days I used Time Machine to revert back to 10.9.
I read some stuff about 10.11 which seemed to indicate that it fixed some of 10.10's slowness issues, so over the weekend I tried to update the iMac again. This, too, failed miserably, with kernel panics and all sorts of horribleness. Given that the machine has never had a clean OS install since I bought it, I figured, why not try that? I plugged in an external hard disk, and did a clean install to that. After it came up (startup disk is now the external drive), it was all fast and snappy. Then I used the Migration Assistant to pull my user data and settings from the Time Machine backup. When that was done, I got the log-in screen. After log-in, I saw that everything was restored. What was cool was that all of the programs which were installed on the machine previously were now restored back to the internal hard drive!
I'm sure there are some things that will need to be properly re-installed (more that just dragging from the old /Applications folder), but the machine seems happy and snappy.
The lesson? It's worth doing a clean install, especially if the machine is older and has had multiple OS upgrades. A lot of cruft accumulates over the years. And if you use Time Machine (and you should), you can get your user data and settings all back without much hassle.
