I switched to vim I was unproductive for days and frustrated. Then I realised I don't have to go thorough this pain there are so many great IDE's out there. 10 years later I am still super productive and don't use vim.
I tried Emacs. I was frustrated and confused and felt stupid. Then I realized I had so many other tools at my disposal, I'd just use those instead. Here I am, 10 years later, happy and not feeling stupid at all! ...but I don't know Emacs.
And don't feel compelled to offer my experience on Emacs other than I struggled to learn it, but plenty seem to find it amazingly powerful. Good for them.
