This is exactly what I needed to take my creative writing projects on-the-go. All I needed was a way to edit and write into my works in progress while traveling and during my other downtime -- DocsToGoStandard is just perfect for that. I work on a document on my computer, save it, sync Documents to Go with my iPhone, edit and write when I can, then sync when I get back. I used to do the same thing using Documents to Go on the Palm Treo and was lamenting that I hadn't found something with the same functionality for iPhone -- then someone suggested Documents to Go for iPhone! Without DocsToGoStandard, I would need to lug my laptop around everywhere, and then I probably still wouldn't get the same amount of editing and writing done on the road.
I love DocsToGoStandard, but it's not perfect. Every now and then I get annoyed by needing to hit multiple buttons to get to something I want (for instance, the keyboard) and it is a little annoying that it does not sync with a folder inside a folder that it is set to sync to. When I'm working on a long document, it doesn't save my place when I close DocsToGoStandard and reopen it, so I lose some time finding my place again.
Like I said, I am really only using DocsToGoStandard for editing Word documents, and it's pretty great for that. I definitely think it was worth the $10 I paid for it.
