If you are not having Microsoft Office anyways installed on your computer, notebook or tablet there is now a way to use Microsoft Office for free.
I had recently purchased Office 365, so i have no real benefit from it. But if you have an internet connection than you can use Microsoft Office Online for absolutely free.
As you can see in the comparison there is no app for it or anything, You just log in to the website and use Office Online. You can even save it to the Microsoft OneDrive of which you will get 7GB on signing up. You do not even require a live or hotmail account any longer. You can do it with Google mail or whatever. Seems Microsoft wants to get a lot of customers on their cloud services…
