Ubuntu needs a simple "Welcome to Ubuntu" dialog after a fresh install that shows you all the common applications that come pre-installed, what they are for, and how I can find them. I don't want to have to go searching for them myself. I'm thinking something along the lines of:
Need a word processor? Use this app...
Need to browse the internet? Use this app...
Need to burn a CD? Use this app...
Want to listen to the radio? Use this app...
Need to organize your music collection? Use this app...
At the bare minimum, tell me about applications that are listed here:
http://www.ubuntu.com/products/whatisubuntu/804features/
The welcome screen should also tell me about the package manager, and how I can find and install new programs - at the bare minimum.
As it is now, new users to Ubuntu are left with a blank desktop and they have to find out how to do things themselves. A welcome screen will get them up and running faster and easier.
