seeing iWork docs in Goodreader
Looks like Goodreader can't yet access iwork.com, but you can put your iWork docs on Dropbox (the new beta version deals with them ok, reportedly) or your iDisk, or even Google Docs (I understand you have to have a paid account to upload nonstandard filetypes, though) and Goodreader can fetch them from there.
You can also turn on file sharing in Goodreader, then wirelessly connect to it from a desktop web browser and upload and download files and even create folders in the Goodreader directory. For this, tap on the Airport icon at the bottom of the Goodreader window.
Personally, I like the iTunes-document-transfer functions in the iTunes Apps tab quite a lot, for Goodreader and iWork. It's fast and easy. The advantage of something like Dropbox is that you always have an updated version of your doc, without having to keep track of where you changed it last--unless you have to upload it from Goodreader after editing, which I have not experimented with yet.
The more I poke around in Goodreader, the more impressed I get.
