Retina compatible Word Processor? Microsoft Office for Mac does not have Retina support, which is a pain to look at while working on documents.
Is there a similar application that delivers the same efficiency and experience as Microsoft Word that has Retina support ?
Just use Pages from Apple instead.

It can also work with .doc(x) files and does even have a better experience. Your can get it through the Mac AppStore. There is also an Excel replacement called Numbers and a Powerpoint replacement called Keynote, all toghether called iWork.

By the way: Microsoft Office for Mac won't become retina ready. At least not the current version.
