Unity

I kept reading and reading Mark Shuttleworth’s post of how Ubuntu plans to replace menus with something called HUD display. And all I could do is take deep sighs. To summarise, in the new “advanced” Ubuntu releases, instead of clicking the traditional menus, you have to type in a few words in a special screen every time, and select from a drop-down which pops down. What is the problem that they are trying to solve?
