Is there an iAnnotate-like app for .docx, .rtf, .doc's ?

Hi, I just got an iPad, and I've heard that iAnnotate is great for annotating PDFs. Is there another recommendable app that works for annotating .docx, .rtf, .doc's ?

Also, I'd like to used such annotating apps w/ a stylus, for underlining text.

Ideas? Suggestions?

Thanks!

Try docs2go in to app store

Great. Thanks! Does it have the same annotation feature that iAnnotate possesses?

By the way, has anyone used a stylus for underlining text (and doing other annotations)?

Wondering how well it works, and if there's a particular stylus out there worth using. I'm used to working w/ very fine point pens...

Hmmm... docs2go doesn't have great reviews. How does Doc² HD compare? Does it do similar stuff? How about its annotation features? Thanks!

I think we're still waiting for the perfect Office app. What I personally do is save my Office files to PDF and annotate the within that app.
