This was the trend which drove me away. I didn't like being effectively forced to "upgrade" to new versions of the OS which changed things around seemingly just for the sake of changing them, pushed me harder toward doing things Apple's way using Apple's services whether I liked it or not, and introduced new limitations on what I could do with a machine that increasingly did not feel like it was actually my computer anymore.

Meanwhile, my clunky old Thinkpad running Linux just kept on getting the job done, enabling me to do whatever I felt like doing... and one day I realized I'd accidentally become a full-time Linux user, because I'd never gotten around to unpacking the Mac after I'd moved.
