I moved to Linux. I didn't care much about the softwares in Windozzzz but Office was something.
I got horrified when I received a .docx. I am doomed, I thought. But to my surprise it opened (with some loss of formatting, doesn't matter).
OpenOffice.org
We all know and love OpenOffice.org. I don't know how I would have finished my final year project without it. KOffice and GOffice have a lot of catching up to do.
Great and simple.
