Microsoft Office is a reliable, versatile computer program. Microsoft Word is the best word processing program I have used. It has a simple user-interface, but also a lot of flexibility in designing and producing files. One complaint is that they often move the location of a few things between versions of Office. Once one is used to where to find something in an older version, it is annoying and a little time-consuming to need to relearn where they placed those things in the new version. Excel works great as a spreadsheet program. I use it to keep track of a lot of our accounting, and it's been reliable and done what I've needed. Powerpoint has the flexibility to produce a professional looking presentation as well as have some fun making presentations. All in all, Office is a little expensive, but if one can afford it, then it is worth the money for the productivity that it provides.
