There are people who say that they have to do some things that can only be done by Excel, or Word, or whatever. There are other people who say that some office suite is what everyone else is using and they can't cope with the constant demands for compatibility help if they use something else.

I love Abiword, and Gnumeric, and LibreOffice. I recognise that general people hate computers and can't understand them, and they want something very familiar. One of the (many) things I'd do if I had the money is create excellent quality documentation for these projects, in a variety of formats, and pay for them to hire researchers / designers.

EDIT: I'm not comfortable using Google products. Partly for the privacy stuff, but mostly because of the online need.
