- It doesn't seem to have a single feature that Emacs (I can't speak for Vim, because I haven't followed its development since switching to Emacs) doesn't. *
- It is tied to one OS. I'm also an OS X user _right now_, but I use other operating systems fairly often, and I definitely need to have my configuration available in those.
- It is proprietary, which means that the day they decide to cut support for it you're fucked.
* I know it is initially more user-friendly, but let's see if you're still using Textmate in 10 years (or have you needed to learn yet another editor), and also let's see if I'm still using Emacs (with all the customizations I've accumulated during that time).
