I don't know why so little information, but the free version has so many limitations such as you can't even print without a watermark or create multiple columns in a document. When you have a fully functioning and full featured free suite like OpenOffice or LibreOffice, why bother with a suite that has limitations?
You're right. You pretty much have to get hold of a pirated copy just to see if it's what you are looking for. Can't tell anything witht the free version. I''ve written the developers about providing a better free version, but did not hear back.
