I need you to understand that I build my own PCs/gaming rig, have been in IT for years, and I've been a full time developer for decades.
The thing about the iPhone is that I DON'T have to think about it. Malware is VERY rare, MUCH more rare than Android, and I DON'T have to worry about...basically anything.
This is coming from a guy running 2 desktops and a laptop. A Windows desktop for gaming, a Linux Desktop for productivity, and a Macbook Pro for the day gig. Oh and I also have a Windows laptop for a mix of everything on the go.
