I agree with the above. It's a free Microsoft Office replacement.
While it's not entirely the same as Microsoft Office, all the buttons and menus are pretty much in the same location so it should even be fine for learning the application with.
Yes �450 is legalised robbery - use Open Office. In a PC Pro review late last year they rated it better than the Microsoft version
Don't forget for your �450 it will only work on one machine , Open Office has no licensing issues so put it on all your machines and your friends and relatives as well
... three cheers for Open Office Hip Hip......
