If you wanted a web-based document/spreadsheet tool, google labs actually has one in Beta that you could try

You can make documents and spreadsheets without the word processor being on the computer, and then go to any computer and the file will be there for you online

http://docs.google.com

Also, you need a Google account, but you can create one there (or if you have a gmail account that works too)

Good luck with the job hunt!
