Well you can officially call me a Vim junkie now!! Having spent the last couple of weeks working with it I can definitely say that I would not work at a machine that did not have it. That's right, that is the same claim I made, and still make, about ReSharper. I still trip myself up in ReSharper with VIM a couple of times, but nothing worth writing home about. To ensure a complete immersion, I have purchased a copy of Vimemu that integrates with:
Visual Studio 2008/2005
As well as now using gvim as my primary text editor (notepad++ is still in the picture) I just recently installed Vimperator which plugs into firefox to give me a whole world of Vim goodness.
There is only one problem with getting used to this tool - You will start wishing you had Vim integration into all of your applications!!!!!
For those of you who are curious, you might get a kick out of the following article: Why, oh WHY, do those #?@! nutheads use vi?
As soon as I have time I am going to give a screencast on using all of these tools.
