Textastic is an advanced code editor
for iPad with rich support for syntax
highlighting, (S)FTP and Dropbox.

I've been avoiding downloading the demo just in case it's ace (I'm sure it is for coding types, but it's a fair few quid to drop on something I'd use primarily for writing words).

I have to use it on one of my servers. Command and insert my arse.
