I don’t mind OneDrive sync, I like it honestly.
What I absolutely do not want, is my Desktop on One Drive. For starters, its often a scratch place. I don’t want it instantly pushing 6GB of photos I just pulled off my camera’s memory card to the cloud before I can sorr them.
I started using it regularly after many previous failed attempts when Twitter died. Same for Pinterest oddly. I use them for similar but distinct things.
