CDE
I like uniformity, simplicity and consistency, stability, few surprises, little guessing. I want to use the computer. I don't need to become an expert in computer interfaces. Like cars. I just want to drive the car. I don't want to have to build or customize my own automobile ergonomics. Much of my time is spent on the command line anyway, but when I have to use the GUI, please make it very simple.
