Coda is nice to look out. But compared to other editors it's years behind. Now I know Panic is working on Coda 2. But I'm not betting the farm on that. Considering Coda has been out for like 5 years. Sure they've released minor updates to keep the current version running on Lion (and bug fixes) but Panic hasn't address anything else really. I could write a LONG list of missing options and features (Like no CSS3 support for one).

And it's damn expensive; $100.00 when emacs is free. Look if you are going to charge for an editor, you better make sure it stays with the times. Something Coda has not.
