I'm borrowing a PC from somebody to write an essay. The laptop is only a couple of years old, but because it's never used, doesn't have Microsoft Office on it. So I need a very basic, free piece of software I can install which will allow me to type basic pages, but save them out to a format which i can then open on my imac, either in Pages.app or a a plain text file. Any suggestions? For the sake of these little jobs I don't want to bother trying to get hold of a cheap copy of Microsoft office... Thanks.
