I couldn't disagree more. I had the hardest time switching over to Vim because there is such a high learning curve, but once it "clicked", I could never back. Sometimes I'll have to do some .Net work in Visual Studio and I feel like I just switched from a Ferrari to a Corolla.

Now, if you're doing work in compiled languages like Java and C#, the code-completion of Visual Studio and Eclipse is very valuable. But besides that, I'd much rather have a simple and fast editor over a bloated IDE with tons of features.
