Gorilla in the Dinner party is the best analogy, classification wise, I can give to Word 2007 for its craving for RAM when used.
Unfortunately Open Office also fall into this family of Human Computer Descendancy (H.C.D for short).
I thought of using the primate family for classification of X-Windows on desktops and accidentally found bonobo (Linux terminology) was one of our ascendant / descendant primates in evolution.
I am currently downloading KDE 4 and fondly name it as the Gorilla of the X-Windows family of descendants.
I have gibbons, orangutans, chimpanzees to add to the family tree.
1. Bonobo is for Fluxbox.
2. Chimpanzee for xFCE
3. Orangutans for the LXDE (our closest ancestor).
This classification is better that the weight class category of human boxers and I will work on this quietly in my reviews in the future.
I welcome your suggestions for the family tree of descendants.
