Same here, buying an ST license is probably the single best SW-related purchase that I've ever done. ST3 works so flawlessly, it's just ironic that it's still technically a beta version. It is actually much less buggy than many "final version" competitors ;-)
On a side note, it is notable how, despite being a closed-source program, ST was able to generate a large ecosystem of open-source plugins; that is not something that happens every day (Jeskola Buzz comes to mind as a similar case: also closed source and with a large open-source plugins ecosystem, but I'm not sure how many people on HN are familiar with tracker-style music software, LOL).
