As a long time Vim user I can pretty much guarantee you didn't learn it in an hour. You may have learned enough to do the very basics but after nearly 10 years of using it I still don't know everything.

I'm sorry for being a bit rash with my statement. I learned to get around vim as fast as in my old editor in 1 hour. Since then I learned to be much more efficient than in my old editor. I don't claim to be a vim expert today either. My point is that as soon as you are as comfortable in vim as in your Notepad++/Coda/Eclipse, etc. you can pat yourself on the back and drop whatever you were using before. From there you'll only get faster/better/more efficient.
