I remember staroffice 5 (its ancient predecessor) in the late 90s. The interface was amazing to my eyes, for the time: http://linuxbook.orbdesigns.com/ch11/images/btlb1114.jpg and http://www.os2ezine.com/v4n3/sointr-1.gif

The star office applications all played well with each other in this shell of an application that looked like windows 95.

This is back when KDE was a new thing and many people were using FVWM ... it just looked so wonderfully sophisticated up against the desktop applications available for linux at the time.
