I have a Writely.com account and when I went there today I was redirected to what is now "Google Office": Writely and Google Spreadsheet are combined on one "web desktop". It is convenient. What I would really like to see is a good online drawing program (like Dia for X Windows or OmniGraffle for the Mac :-) I often need simple drawing embedded in my writing and I would bet that I will not have to wait too long for a web based figure/drawing functionality.
