I came here looking for a notes app that synced with Dropbox, like Notesy or something. I wasnt looking to edit code (although I am a programmer), but when I saw the reviews, and the features, I thought Id give it try. This editor blows away anything like a normal notes app. Its in a whole other league. If all you want to do is edit text files, and you are a "normal" (non programmer) user, maybe its overkill, but honestly its great for the simple stuff, and the price is similar to notes apps. But then there is SFTP and SSH? Wow. Syntax highlighting for code? Wow. Other great stuff too. I have not tried other "text editors" (as opposed to "notes apps") for iOS, but this is way beyond what I was looking for, and thats a good thing as far as I am concerned!
