I paid for Textmate too, for Textmate I. That being said, I'm sad that the development of Textmate has come to an end. Switching to another editor sooner or later won't be easy.
I recently also switched to Sublime Text 2, and while there are still a couple of hiccups, overall it has been an awesome editor to use. It's global search is blindingly fast, saving me tons of time while developing. Definitely recommend switching when you have a few hours of free time.
Switch to http://www.sublimetext.com/, It will be the best decision you ever made. Its what textmate 2 should have been
Thanks, SublimeText is certainly a possible candidate. For the moment, I can still use Textmate 1. That gives me some time to test other editors including SublimeText.
How can you be sure Sublime won't go the same way TextMate went? Personally, I'll go with Aquamacs.
