You should try http://sublimetext.com

It's sort of like textmate but also cross-platform, so in theory you won't have to learn another editor. I'd learn it myself if I wasn't already used to textmate.

I like this editor a lot also. Sublime Text 2 is quite nice. Enables me to use a nice editor across all of the platforms on which I have to develop.
