I actually am planning to switch to annual plan, but not for auto - just for Tab autocomplete 
I was using Cursor for almost a year now and at first I was contemplating if it’s worth. I came from my comfy neovim with supermaven and stuff so the switch was kinda painful, but the superiority of Tab gave me a reason to try it longer and stay.
And for some months I was looking back at my experience and haven’t found any reason to leave or wait for a Tab only plan. So, annual subscription it is. At least it won’t be $20 / mo anymore lol.
And unlimited auto is just a bonus in my case, although I can’t see me using it much so it would make a difference
