SM, I wasn't addressing the thread's vulnerability problem, about which I know very little. Rather, I was addressing RinaseaofDs:

"Maybe they can fix the deprecation routine that slows the PC down gradually over time until it simply fails to run anymore.I never understood why a perfectly good computer running a limited number of application gradually slows to the point of unusability."

Frankly, I talked about apps -- rather than come right out and say that Apple's coding discipline enforces memory cleanup far more rigorously than Microsoft's does -- or, ever has -- including at the system level...

Maintaining runtime memory cleanup coding discipline is a PITA, but it pays off in long-term satisfaction. Example: my MBP runs for months without ever being shut down -- without any perceivable performance hit...

I can't speak to system slowing re: Apple products. What I found most memorable when I started up my first Mac laptop @8 years ago was the speed of loading its programs compared to any Microsoft system. It was then that I understood what Steve Jobs was all about. Next was the elegant, simple user interface. My favorite product and most used is/was my iPad1. On that version, the Settings are all on one screen where the average person can understand where to go. Now, on iPhones and iPads, the simplicity has been lost. Steve Jobs looked through the eyes of a neophyte and the artist when designing products. Sadly, no one is there to take his place.
