I usually enjoyed and trusted Wei-Meng's articles. this one convinced me to try OpenOffice and the X11 beta.
A (surprisingly) perfectly smooth installation and start of Open Office. It read my Microsoft .doc and .xls the way I expected. Found my laserprint and printed well.
For info I worked on a Titanium Powerbook G4 with OSX 10.2.4, HP LaserJet 1200. Also I am not Unix-savy. I could be classified as the business guy.
I will this a SERIOUS trial and let you know in one month from here.
