Life may be too short to struggle fruitlessly, but certainly not to struggle towards solutions. Perhaps my tone above was frustrated and complaint-ridden, but that arises from a time, iOS6 to be precise, when iOS did not behave this way and had allowed many of us to develop a useful workflow without having to worry about random page refreshes and app reboots when switching apps.
I stay with these products because, as you say, the needs and demands of the workplace and social life as well are complex. My Apple devices work fairly well integrating much of the data that I use daily, they are reliable, and they are well-made. It is really scholarly work that I find difficult now on the iOS that was not so much so in the past. And what is specifically difficult there is web-based research and Internet forum interactions, for me anyway.
I hope your thinly veiled "love it or leave it" stance is also merely one of frustration with the friction on this issue. There are 65 pages of griping on this issue here, and there is a reason for that. The griping is a labor of love at its core, because, as you imply, it'd be easy to walk out the door.
