It's a temporary solution, and not the most elegant, but Google Docs works quite well from the Pre's browser. I have been able to create and edit spreadsheets, word processing docs, even presentations from within the browser using Google Docs.

I have not been able to successfully save a new spreadsheet, but if I create one on my pc through the browser, I can edit it on the Pre lickety-split and save it. For whatever reason, saving a new Document, Presentation, or Form is no problem but Spreadsheets are a little goofy.

So, for now, I can edit docs I need to access regularly (business expenses spreadsheet) through the browser. Like I said, not elegant, not perfect - but it works!
