I bought a license for TextEdit 4 a few years back, but although it is fast and nice to have around, I never really loved it. I also switched to OSX at home recentlty and haven't really found a text editor I like, though JEdit comes closest. It is cross-platform and has a few useful plugins for perl, but it works best with a big screen. My MacBook's screen isn't really big enough for it if you a lot of plugins.
