"All three of my children have tried OpenOffice, and all three of them, after a few days, have come back and said "Daddy, please can I have a copy of the real Office"?"
I'm sure its true but must you trot this little story out every few months?
My (and the neighbours kids) son has been using OpenOffice (and now Libreoffice) for several years and doesn't seem to have any problems.
