I've used Microsoft Office Professional for decades. For my business needs, it was an absolute necessity. Early on I tried Wordperfect and a variety of spreadsheet alternatives but they never quite measured up. Now, we've got a good product that has been improved and I'm glad to have gone to the expense of upgrading to this new professional version even though I am retired. There are enough improvements in each of the programs included in this suite of software to make me satisfied with this purchase.
