But how about:
editing MS Office documents
Well, for your service (

, I have just tried out the online version of Microsoft Office under MorphOS (OWB spoofing as Chrome).
The online version of MS Office is reduced in features (as seen in the screen shots below); it's kind of rudimentary actually. I think Microsoft's idea with it, is that should function as a way to edit already existing documents created in the "full" version of MS Office (and saved on Sky Drive), rather than functioning as a free, online office *replacement*.
So to answer your question - sure *you can* "edit MS Office documents" on MorphOS this way. It can feel a bit sluggish compared to having the real MS Office on a Windows box, some things more than other (like key repeating, and the fact that it auto-saves your work on a regular basis, which takes a second or two), and the application is prone to crash in some circumstances (like when opening the font selector and closing it again without selecting a font). When the application crash, it restarts, and recreates your document from the latest save point (or auto-save point).
Word works quite OK for what it's meant to do. It's nothing I'd write a book on though!

PowerPoint is kind of OK as well. Excel is IMHO the app which suffers the most from the feature stripping.
I made some pictures!

MS WordJust typing some headline, text, and trying the various fonts

Going to insert some clip art. Searching for a butterfly, and find a nice blue one! ;-)

It was kind of big, so reducing it to 50%

Spellchecker doesn't like the word "MorphOS"! Huh?! ;-)

But changing the dictionary language to Swedish...

...renders a whole lot more errors! :-)

MS PowerPointSelecting a theme for my new presentation

Entering a title and subtitle in the presentation's title slide

Entering some text into the new slide

New slide with two columns. Entering notes in the note field at the bottom of the screen, trying out how formated text works there. Inserting a blue butterfly from the clip art, and selecting a tilted picture effect for it

Entering a slide title and some points in the left column

Hitting the "show slide show" button. Imagine if this would have opened up in full screen mode instead of inside the browser! :-)

MS ExcelEntering some data, changing the width of some columns

Going to insert a diagram

Diagram inserted, but going to need some editing before I'm satisfied with it

Diagram edited (new title, etc) and repositioned in the spreadsheet

Just trying out some more formating options

There is another Microsoft office application available there as well, "MS OneNote". I have no idea what that is. Have never used in in the "real" Office, and I haven't looked at it here either...
So, There!
