The pop superstar received the gadget; a computer build into a 30-inch tabletop touch screen display which allows users to move digital pictures across the table with their fingers - as a thank you gift for recording the song Hey You for Live Earth.

"Steve Ballmer of Microsoft has sent me one of the best gifts I have ever received! It is called "Surface," writes Madonna on her website. "It is a coffee-table shaped computer that responds to touch".

"In addition to thumbing through thousands of my favourite family photos, I can listen to my music collection watch videos, etc. My children have also had a blast fingerpainting without getting their hands dirty!"

"Steve jokingly referred to my post about the Xbox 360 Degrees! He said, "I assure you this product will not overheat!" I hope not! I will let you know if anything goes wrong with it!"
