I agree with Cinnamon being polished and deserving much more attention than it currently gets - but what stops me from using it is the impossibility of arranging the virtual desktops (workspaces) vertically Gnome style and the refusal of the Cinnamon devs to implement that - I for one cannot get myself to horizontal workspaces, especially after using Gnome. Some extensions did provide this in Cinnamon but the functionality appears half-baked and the extensions break after each Cinnamon release.

I switched to Cinnamon on Ubuntu after struggling with Unity for six months. Works perfectly, and personally, i much prefer it to Unity.
