2. 知道 Ubuntu 的 No.1 bug 是什么吗——Microsoft has a majority market share：

Microsoft has a majority market share in the new desktop PC marketplace. This 
is a bug, which Ubuntu is designed to fix.

Non-free software is holding back innovation in the IT industry, restricting access 
to IT to a small part of the world's population and limiting the ability of software 
developers to reach their full potential, globally. This bug is widely evident in 
the PC industry.
  Steps to repeat:
    1. Visit a local PC store.
  What happens:
    2. Observe that a majority of PCs for sale have non-free software pre-installed.
    3. Observe very few PCs with Ubuntu and free software pre-installed.
  What should happen:
    1. A majority of the PCs for sale should include only free software like Ubuntu.
    2. Ubuntu should be marketed in a way such that its amazing features and 
benefits would be apparent and known by all.
    3. The system shall become more and more user friendly as time passes.
