I use GoDocs to edit word documents, stanza to read all my pdf's and ppt presentations, hmm. I use the basic notes application to take notes down during class, and my lecturer emails me her keynote presentations for me to read on my keynote.haha

Documents to go is pretty good, i even use it to edit word docs. All in all it's a useful tool, but not vital. If u can afford it, why not bring it along to work? I'm a ollege student and it's great fr just slotting in between my books and for tsking notes, and games, and social networking. Oh, and browsingg.
