Microsoft has launched a US marketing offer for people to exchange "gently used" iPads for Microsoft products such as Surface tablets.

The company is offering at least a $200 token to go towards products such as the Surface RT and the Surface Pro.

Microsoft is far behind Apple in terms of global tablet sales and market share.

One US-based analyst expressed doubts that many people would swap their iPad for a Microsoft product.

"Do I think that many people will take [Microsoft] up on this offer? In a word, no," said Gartner mobile device analyst Van Baker. "The app ecosystem is the problem for Microsoft and this offer doesn't fix that problem."

There was a far greater range of mobile apps available for iPads than for Windows devices, giving Apple a competitive edge, said Mr Baker.
