Thanks scottjl, I forgot about the upgrade path, that may have been what someone was talking about.... The full Pro version is $15... for that you get compatibility with Word, Excel and Powerpoint. And others as well..... I don't use the PowerPoint to do anything but view... but the Word and Excel parts edit very nicely.
Please understand you are not going to get the full MS Office experience for $15.... but it is darn good... I wish MS would make a MS Office "lite" for iPad... but if they did it would be overpriced and the bottom line is they will never do it.....
