Cursive Writing Is Really Important?

The other day I saw my cousin when doing his home work.
He is in third standard and asked me to help for his project about water pollution.
We prepared chart and I told him to write the information, he wrote them in cursive hand writing.
I informed him not to use joint letters in charts, it can't be understood by everyone clearly.
Then he wrote in separate letters, but cursive letters.
I wondered. Then I asked him to write in ordinary letters.
He said that he doesn't know how to write in normal letters.
It was a real shock for me.
Then I started thinking on this subject.
I can't write in cursive letters and even joint. We did not learn that in school.
But I have never felt any difference in study or work.

I find really hard to read when someone writes in cursive writing, only that is the difference I felt in cursive writing.
This link debates for the importance of having cursive writing.
But what I feel is that those points, Except the one which says it is good for our mind,are not valid enough to support 'cursive writing is must'
And I strongly disagree to the decision of some schools to teach the children to write only in cursive writing.
This post explains cursive writing as an art and it satisfies my mind.
So what do you think about cursive writing?
I am interested to know.
