Hey Kevin,
Yeah, I agree. HTML Kit is a strong peice of work. For being free, he/she/they did a great job. I expect to see it rise to somewhere near the top of the heap as development proceeds.
Perhaps they should create a Linux version as that's where I work most of the time.
That said, I like (in Linux) CoolEdit, Anjuta (for the Objective C stuff that I'm learning), Nano, and BlueFish.
Later on,
Big Din K.R.
