Sublime Text 2 is awesome - easily my favourite text editor. My only concern is that you will not make nearly enough conversions from your unlimited evaluation with your current pricing scheme. $60 will be considered by most as waaaay too high for a text editor, especially when there is no real incentive to buy. I would suggest lowering the regular price significantly (maybe as low as even $10-15. Just look at Steam's pricing for games - this is a price bracket that many people are comfortable with and Valve is now valued at something like $6bn) whilst keeping the $60 fee as a "developer licence". I don't think there would be many enterprise users that would opt for the cheaper license fee just to save money, and I think you'd get many more conversions from regular users if you adopted this model.
As I mentioned, I'm a genuine fan and my suggestions are only an attempt to make sure you reap the benefits of your hard work effectively.
