I'm a vim stan. I love my vim. I still end up installing nano on all my machines. It's honestly not even for me anymore, it's for anyone else who happens to use it. Vim is great but it's got a learning curve.
Often times I'll just use vi, since it's always there.
Like two or three weeks for most tasks. I still check the manual sometimes, it's built in :)
