This is the programmer/IDE-dweeb's version of "well yeah.. but does it run Linux?" Only half joking; the parent's comment is exactly what I thought after searching through the feature list.
It's funny how, when forced to work outside of vim, the first thing I (and at least one other person, it would seem) do is try to make the environment as vim-like as possible (with usually-mixed-to-unsatisfactory results).
Eclipse and Visual Studio are the only IDEs I can think of that, outside of The True Vim, support the "vim-like" editing paragidm with any robustness (viemu on VS2008 ($), vsvim on VS2010(free-as-in-beer).. I forget the name of Eclipse's premiere VS plugin.. but I know it's in the gallery.. there's also the "embed a vim window in Eclipse" thing, but I found it somewhat ackward). MonoDevelop has a core-support vim plugin, as well, but it's not-quite-there, yet (as of 2.6).
Anyone else have any preferred "not-vim-but-vim-like" editors, when forced to work outside of The Better IDE? (And I don't want to hear that viper-mode shit, either. It's a False Vim and you know it.. like the snake that tempted Adam and Eve into Sin!).
I use VsVim on a daily basis, and really like it, but I've also found that it can bog down the IDE a bit at times (especially if you've left VS running but are doing other things for awhile). It's not a deal-breaker for me, though.
Every time I see a new shiny text editor for mac, I'm like "meh". I would have been excited in my pre-vim days, but now? Nothing touches vim, unless it improves on vim.
