Huge Windows Vista ad on Shanghai's Jinmao Tower

This photo was taken by Shanghai blogger Jakob Montrasio on Saturday. He writes:

I could not believe my eyes when we left the “Banana Leaf” restaurant in Shanghai’s Pudong district yesterday - there was a huge advertising on the 421 meter high Jin Mao Tower! On one of the biggest skyscrapers in Asia! Yes, it makes absolutely sense to advertise like that in the country where you can buy a copy of Vista for about one dollar. Whatever Microsoft!

A commenter over at Flickr wrote:

Hmmm. I wonder how often the tower needs to reboot.

We just want to know how much the ad cost. We assume slightly more than one of our Skyscrapers.
