Thanks for the opportunity to express some thoughts.
I am a structural engineer in the precast concrete field.
I have been using and writing computer programs since 1970.
I have been using Kubuntu for my Qt programing.
When I upgraded to Kubuntu 8.10 from my Kubuntu 8.04, I was shocked at the complexity of the enhancements. (KDE 3 to KDE 4).
I switched to Ubuntu 8.10 and was pleasantly surprised. I could use it out of the box!
