I decide to used open office but when come to save it as I want send to my friends who have mircosoft excel as he was saying that the data was wrong when I using Libreoffice when come saving it and sending to him. He check it and there were some wrong numbers even thought they were correct number in libre office:roll:
I used a lot of opensource office clones (like OpenOffice, LibreOffice and Kingston office). All is good for basic usage but for professional usage I couldn't any of those productively.
After getting used to the ribbon 2007+ I kinda hate going back (I never thought I was gonna say that).
From 2010+ the quick paste features, the nice pivoting, ODBC data mining from endless sources with autoformating are awesome stuff.
Can't beat the free nontheless for basic usage though
