Why buy MS Office? (Score 1)

... when you can get LibreOffice or OpenOffice for free - OpenSource?

I've been using OpenOffice, or it's fork/successor LibreOffice for years. (Lots of interesting stories about the LibreOffice/OpenOffice split. Note: the comparison article mentioned is waaay out of date)

I give the nod currently to LibreOffice v3.5, which was just released, but we'll see what Apache does with OpenOffice ('Incubating' at v3.3).
