I don't think it's the office suite holding people back. It's that plain text editors feel clunky in Linux when you were introduced to text editing in Windows. Something like EditPad Lite Linux would go a long way to alleviate the strangeness.
People don't want to learn bizarre key bindings just to dash off an email. I did Linux for a few years. Various releases of Slackware, Redhat, Mandrake etc.. But it still felt awkward because of the text editing. I used kylix IDE for text editing just because it had Windows key binding set by default.
Without Windows text editor key bindings the only way to get people on Linux is to send them to Linux brainwash camp to learn text editing when they first learn to read.
