Can anyone provide something like a big picture about HMTL5?

According to the article in wikipedia[1] HTML5 gives us so far:

Some new elements, more values for @type in input,
Formalization of parsing rules (that is simple a definition
of HTML5 grammar).

What does HTML5 change in principle (if it has to change anything)?
What we will tell to John the Plumber if he would ask us "why HTML5"?
What problems HTML5 solves now and what foundation it creates for future 
if to compare with HTML4?
