You beat me to it. I use Open Office and tried Libre Office but preferred Open after some side-by-side comparisons. I am so used to Open that I would hesitate to try anything else. It reads and writes to Excel and other formats. Plus It runs on Linux, Windows, and OS X. Having said all of the above, I really miss Lotus 1-2-3.
