I'm all for supporting good, independent software shops, but $70 for a ST2 license is obscene. I use the free version and would happily pay to remove the "Buy Me!" popup at a lower price point.
Then again, I assume they considered this carefully and made an informed decision when they set their price point. I'm definitely in the "I'd buy it if it were cheaper" club, though.
SublimeText seems to be the same kind of editor: you pay for it (a hefty price), it brings you features, but it's still very young, non-standard, non-ubiquitous and seems to be going at too fast a pace for its own good.
My bet is that as good as it is and as much as it wants to be the new vim or emacs, those editors will still be around in 20 years from now, because they've been thoroughly tested, augmented, improved upon, they're free in all sense of the word and they benefit from HUGE ecosystems of plugin developers, sane choices of underlying language support for scripting and customization (vim less so than emacs but you get the point), i.e. they deliver HUGE value.
Oh come on. I think that's a very fair price if it's a tool you'd use daily (especially in a professional capacity).
I can't think of any other job where you could even try the tools for free, much less complain about them being 70$.
