I have nothing against MS, but I'm all for competition. If more people start using OO, as I am now on 3 of our 4 machines, there will eventually be less people encountering the incompatibility problems. I am happy with it and mye wonderful computer man tells me that it's as good, if not better, than MS Office 2007, bar the potential compatibility problems. As my use is very simple, I don't even know what a macro is, I don't envisage any problems.
