Regarding hardware quality:

  "...why there's no PC manufacturers that would
  have the same overall quality of the hardware."

In my experience, business ThinkPads beat MacBooks by a mile for working (e.g. programming). I am surprised to see so many coders use MacBooks. Thinkpads have better ergonomics, are more robust and better performance/configurable hardware (e.g. RAM).
