I am owner of Microsoft Office 2010 for PC and Microsoft Office 2011 for Mac. The MAC version is less ergonomic than the PC version. The review mode, in particular, can not be set so that the deletions are crossed out in the text and comments appear in bubbles (or both appear in bubbles or deletions appear to be barred and comments ... not appear ...). This may seem a detail but it is very useful in everyday life.
But ESPECIALLY, the Mac version is considerably buggy. Unable to work in review mode on a document without a crash about every hour ... Simply shameful on the part of Microsoft. The only reason I do not go on for pages is due to compatibility.
