I like that all my settings and preferences transfer between computers, and that stuff like OneDrive is easily accessible from modern-era Microsoft software, which makes it very easy to get at files from my phone or on other machines when necessary.
I actually sync with OneDrive to my MBP.
Yeah, there's some cost for the convenience, but whatever... there are aspects of life where I fight to keep my privacy or my rights, but in other areas, the convenience gained is worth it imho. Google/Android has helped make things so easy for me on the go. Besides, what corporations like Google and Microsoft have on me is nothing worse than what is already in some government database somewhere (part of which is now, apparently, in the hands of the Chinese... thanks government!).
