This is really not true anymore of Windows. Windows 10 is a much better product now and has come a long way. I work with Windows everyday and rarely see the issues I used to. But I do agree MacOS is better.
I used Windows 10 for 3 straight weeks, recently. It's still in the 80s in many respects.
1. Can't rename or move a file in the Explorer that is open. You get an error message. You have to go find the open file in an app and close it. If it's over the network, go find the person who has it open and ask them to close it. Horrible.
2. Open/Save dialogue is exactly the same that it has been for 20 years, and it sucks. Different apps give you a different open/save dialogue. Different apps give you different open/save dialogues, so there is no OS consistency. They don't remember where I just was 10 minutes ago, so I have to travel through C:/Documents/Project Folder/Images... CONSTANTLY!!!! The Mac has an open/save that reflects the FAVORITES that's in the Finder, and it has a RECENTS pop-up menu for me...in every app on the Mac. It's superior. And I spend a HUGE amount of time in the open/save dialogues.
3. Can't drag/drop files onto an app in the task bar – you really have to behave like it's 1988 in Windows, to this day. If you have Photoshop open and it's in the task bar, and then you go to the Explorer to look at files in your folder and find a JPEG you want to open in Photoshop, you can't just click and drag it onto the Photoshop app icon in the task bar to open it in Photoshop like you can on the Mac. You have to either right-click on the file, select Open With... and then select Photoshop in the long list of apps, or you have to go back to Photoshop and select Open... and find that file you were just looking at.
4. I printed a project from InDesign. What's the status of that print in Windows versus OS X? It's shocking, the difference. The Mac OS automatically brings up a dialogue of that print and when it's finished, it disappears. With Windows, you gotta find the printer in the Control Panel and then open it up and then select the printer and then close it when it's done.
5. Switching between apps is a pain in the butt. Windows has you switching between windows, not apps. Clicking on the app in the task bar shows you a thumb of all windows open in that app.
6. Windows 10 still has TWO control panels! LOL. Control Panel/Settings. Seriously, to illustrate how awful Microsoft is with user interfaces, just go through the control panels and settings for your computer.
I could go on and on and on.
In short, the Mac OS is SO MUCH MORE efficient than Windows.
In regards to all the system hassles, viruses/malware/spware, I reject the notion that Windows 10 doesn't have the same issues earlier Windows had. I experienced some myself in the 3 weeks I worked with it and watched the IT guy fix them.
Windows is still total crap. It had been years since I used it on a daily basis for a project and I was shocked at how antiquated it still is. Believe me, I would LOVE to be able to go build a custom PC with the latest GPU and configure my hardware however I want and have the same every-day experience I have with Mac OS. I will shout it out to the sky if this happens with Windows. Unfortunately, I'm still picking inferior Mac hardware for superior OS.
