Apple's MP3 Player the iPod is billed as the star attraction at the event that takes place at Canary Wharf in London’s Docklands from December 2 to 7.
This is the first GadgetExpo to take place, and attendance is free.
GadgetExpo sales director Ryan Scantlebury said: "We want to develop GadgetExpo over the next five years into a popular, cutting edge expo, with the very latest products – such as the solutions supplied by Apple."
Apple reseller John Lewis will have a large presence at the show. It will use the event to showcase the iMac, iBook and iPod ranges, and Apple’s suite of digital-lifestyle applications.
