This is a great space to be in. It seems that O365 is growing leaps and bounds and many feel out of control when everything goes into the cloud. It's good to have additional security options.
MS seems to be trying to get rid of installed office... I was luckily able to get one of the last copies of real office with our work discount before they only now allow O365 where you pay yearly... I now have two copies of office pro plus real full office suite... one I didn't really need but the price is so good I went ahead and picked up another copy before it became extinct.
