The reason I switched from TextMate to Vim was simple: portability. I can keep my environments at work (Windows) and home (OSX) the same. Editors naturally prompt a deep investment in studying, plug-in finding, and muscle memory if you really want to use them to their fullest. I didn't want to split my investment between TextMate and <some Windows editor>, so I started the long process of getting familiar with Vim. I do miss some of the native flavor of TextMate, but the comfort of having my entire suite of plug-ins and shortcuts apply virtually anywhere (e.g. logged into some VPS) is really helpful. If I was mostly in OSX it would be a different story, but for the cross-platform developer, I really think the Vim and Emacs options are the way to go.
