I have a gmail account therefore have the Google spreadsheet. Neat thing is that you can set it with permissions so that others can use it, or modify it, or not, or share it however you want. And the thing is stored and backed up on their computers...you have no program, no need to save it and back it up..etc.

Other than that I often work in Open Office and store the result on Google....
