I didn't have enough time to start anything fun last night, so I had a quick mess around with some of Google's office apps. I remember when they came out and they were pretty unusable, or maybe that was just because I was trying on a phone screen. I have to say, now, I'm really quite impressed at them. The word processor, Docs, is a nice, clean working environment for writing. Although it does seem to lack some things that are found in the full web based version, such as inserting images. Same story for Slides, the presentation app. You can't really make presentations without images. They do, however, both seem to render files that were made elsewhere (Libre, Microsoft) exceptionally well. Sheets, for spreadsheets is also nice, but lacks a lot of functionality you'd expect in that kind of software, including plotting and macro scripting.
To me, you may be asking a bit too much to expect to be able to make great content from scratch, but they are very useful for viewing and manipulating. I can see me plugging the HDMI lead in to show a presentation I'd made with Libre, knowing it'd look great.
