Except Libre office has much better functionality, even though its less on price.
I'd just like to issue a counter-argument. I use word processors... well, basically only ever to read stuff other people have made, and then rarely. Almost all of my writing is done in plain text, in HTML, or in Latex.
But what I do use office suites for with some regularity is presentations. And to be honest, IMO Impress doesn't even hold a candle to PowerPoint. A few years ago I was gearing up for something which I expected would need me to make a lot of presentations. (Turns out I did something different, but whatever.) I spent a fair bit of time just trying to use both PPT and Impress, so I could figure out which I wanted to use. And for whatever reason, Impress was just really frustrating to use. At the time, it was far worse than even old versions of PPT, and 2007 was (I think) a large improvement over 2003 for reasons other than the ribbon. (Actually even 2010 made some very nice UI improvements over 2007, which surprised me.) The situation is a bit better now with Impress, but it's still not even close IMO.
PowerPoint has some problems, and it's not really the presentation software that I actually want. But it's still worlds better than Impress. (I'd like to try Keynote, but my usual line there is I don't want to spend $1000 on presentation software, even if it does come with a free computer. :-))
(For all the Beamer fans out there, as much as I like Latex for other things, I think it's kind of crazy for presentations. IMO, presentations are a medium where Latex's strengths are unimportant and its weaknesses are important.)
(Also, just to be clear, I am somewhat a MS fanboy by /. standards, but my closest relation with them was failing to get an internship with them not quite a decade ago.)
