There is new version of Office available and this one cost $0

A new version of Office is now available. And there are three big changes, in file format, price, and spam
filtering.

The features aren’t much changed from the last version. There are some new options, sure, and some bug fixes, but overall this is the same bundle of
word-processing, numbers-spreadsheeting, charts-presenting powers that most everyone with a computer needs, either every day or at least once in a
while.

So is it worth upgrading from your current Office?

Well, the file format change is important. The new Office is built on the new open XML standard. (Say it one letter at a time – “Ex Em El” – not as a
single syllable like “Ximmel.”)
