One anecdote: I upgraded my sister's Macbook to Sierra and guess what happened... suspend stopped working :) Moreover there was one process using 80% of CPU all the time which made the system unusable. Based on the fact that I found dozens of pages about the problem I suspect it's a common bug. It was easily solvable for me, but nothing my sister herself could cope with. So the Mac world is not all ideal, it has bugs, quite a few bugs. For example, upgrade of my work laptop to Fedora 25 was, in fact, much less disruptive than the upgrade to Sierra. Battery life really depends on model. When I got a brand-new ThinkPad X240 it lasted 10-12 hours of normal usage on battery, up to 16 hours in the airplane mode. I don't find that too bad. Of course, if you buy a laptop which was built for and only for another OS (e.g. Macbook), it's hard to achieve the same level of power management with a different OS. Jiri
