Am I foolish for not believing the vi/vim hype?Not at all. If VS suits your needs, then rock on!
Personally, I enjoy the occasional vi/vim story here, as in reading the comments I almost always come away with several new ways of doing things in vim.
I think there's a better question to be asked, however. Given that programming involves a seemingly endless stream of tools/techniques that seem good enough and alternatives that are promised to be much better, do you have an efficient strategy for determining which alternatives to explore? (This is a question I've been wrestling with myself recently.) How much time should be budgeting for exploring an alternative before writing it off as a time sink instead of productivity multiplier?
In your case, since you already use vi/vim daily for some editing tasks, I'd suggest a low time-investment strategy of lowering the slope of your learning curve: review how you normally use it, isolate one or two procedures that seem awkward or irritating, and then focus a small amount of time on researching/practicing the recommended alternative practices of experienced users. I've found that by focusing on the occasional experiment, learning is much more enjoyable. If I think about how much I don't know about vim, on the other hand, I'm inclined to feel overwhelmed and put off learning anything.
Admittedly, this approach isn't going to help if your resistance point is learning to dump the arrow keys and mouse. On that one, I don't know that there really is any good alternative to a couple of weeks of devoted effort.
