They seem to have defined their target user, and design around it. And I think most of us are not this target user.

I have used Coda since 1.0, but later switched to TextMate and now, Sublime Text. And eventually, I replaced all the good parts of Coda with something that wouldn't work with Coda as well:

- I write Ruby, not PHP, and it's not one-input-file-equals-one-output-file at all. So preview is not that useful. Completion probably won't work for Ruby as well as for PHP, and so on.

- I don't write CSS or JS anymore, and I don't think I could live without my SCSS or CoffeeScript (well, I can, but it's painful). So all the fancy CSS GUI pop-ups don't help, I have a probably even better solution in code and mixins.

- Finally, all the UI seems to be Novice-friendly, with sidebars and tabs, while I don't even have a sidebar at all on ST2, and just use Cmd+T for opening / switching files.

Also, as for the site itself, the demo tour looks awesome (even though a bit crammed).

All the best to them! I won't be upgrading, but I think many will find Coda 2 a great improvement.

P.S. I love that they list app being "Retina-Ready" while we still don't have any retina Macs yet :)
