In my opinion, not at all. I have stopped using Mac ages ago, and must admit that the "integration" was never a strong advantage in my workflow, and didn't miss any of it when I moved to Windows.(no but really...just hear me out...)
So as an engineer who has been immersed in the MAC world my entire adult life, I finally had to come to face with reality that I needed a workstation laptop for the type of work I do.
So I ordered myself a Thinkpad, sold the MBP and now I sit with an iPhone still.
Wanted to ask the community, should I keep it, any reason not to? Or should I be swapping it for a non Apple based OS phone?
Is the iPhone pointless when the integration of having their other devices is gone?
On the other hand, I find iOS/iPhone to still be by far the best mobile experience for my needs, with great OS stability and most importantly, app quality.
