The iPod touch seems set to be a mass-market smash this Christmas, at least according to Toys R Us.

The toy chain has revealed its annual top 20 list of products it expects will emerge as the best sellers this year. This year the list is dominated by electrical gadgets and TV show spin-offs.

The retailer expects the iPod touch will become the most popular electronics item at Christmas this year - eclipsing the previous leader, the iPod nano.
