Some weeks ago i installed KUbuntu at work to help improving the multi-OS behaviour of our Qt based product.
What is interesting is to know which things they have liked more about KDE, first are konqueror shortchuts gg: imdb: en2es: es2en:, second there is RSIBreak, they like that cute program that helps you avoid RSI, and third and finally they woed about ... kruler!!!
So for all those that say that those little "toys" are not good for KDE shut up, i got office people interested in KDE with all those small progams ;-)
