This is not what i would call a 'review'. It's a performance comparison between these four packages and nothing else. If the only thing that matters to you is how fast your .doc opens it's fine, but i guess for most people things like compatibility and UI are more important...
Not sure that RAM or CPU usage are ever going to be at top of my list when it comes to evaluating a word processing package. I don't even care as long as it's below 1gb ram and uses less than a whole core, the embarrassment of riches in the average computer today makes it a non-issue.
> features are not as important since all of the software here has the features we want and used for years!<p>No. No it does not. LibreOffice/OpenOffice still lack essential basics, the big one for me being style sheets (I believe iWorks fails at this as well). Yes, they have basic support for styles, but beyond the basics, they lack quite a bit. Maybe it's changed in the last year, but I've yet to see anyone note better support for styles.<p>At the same time, iWorks pales in comparison to Office 2011 for Mac. Take Word's full screen mode compared to Pages: Word is dramatically better.
