Microsoft goodbye. Check out SoftMaker Office.
Why would anyone buy Microsoft Office 2013 or upgrade? Because of the fun to try and find out which menu the command you want use has been moved to now?
Or because Microsoft seems to think it improves my productivity, having to learn to use 3 different versions in parallel, because I have an office desktop, a home PC, and a netbook?
Or because I have to buy three versions with each just one license? Btw., each office-suite is tied to the system. If a new PC has to be bought, you will have to buy a new office suite, because your product key will be invalid. You don`t believe me? Read this:

There are better alternatives. OpenOffice and LibreOffice are free, but laggy, and they both have problems with several Microsoft formats. FreeOffice does better. If you invest a little money, you get SoftMaker office Professional, including 3 licenses, and EM Client 5 Professional. This one works great, you can import and export Microsoft Office file types without loss. I recommend it also for its ease of use and broad functionality.
Biting the hand that feeds IT
