What is a good, preferably free, Office Suite for the Ipod Touch?

I don't own an iPod Touch yet, but I'm particularly interested in a portable Office suite that can open, edit, and save Microsoft Office 2007 Documents, Spreadsheets, and Presentations without requiring a constant internet connection, such as GoogleDocs. Otherwise, I think that I may just purchase a Nokia N800 Internet Tablet.|||There is an office suite for iPod Touch, QuickOffice. It is pretty good reviews and you can edit documents offline.
