Former Mac / iOS user (since pre-G3 Macs and the iPod touch), it's not that hard to switch. My main devices are now a Surface Pro and a Z3 Compact.
With how much data has moved off of devices, losing data isn't a huge concern anymore. My mail, calendar, photos, etc. were already hosted elsewhere on services with cross platform support.
Cost of replacing apps is the bigger issue, and for me it worked out to something under $50. That was cheaper than the (~$200) cost premium of a 64 GB iPhone over the Z3C and a microSD card.
EDIT: If you've tied yourself into HomeKit or Apple's photo system, things would be worse. Maybe I'm atypical there?
