UK shoppers will buy 50 million digital gadgets this Christmas, according to research by Crucial Technology, a supplier of memory upgrades.
Meanwhile an estimated 1.2 billion photos will be taken during the Christmas period using a digital camera or cameraphone.
Other big sellers this year are expected to be CDs (154.3 million), DVDs (130 million), and video games (43.6 million).
But the research suggests that millions of people could lose music and picture files held on their new gadgets.
Seven of the devices in the top 10 of predicted sales require the use of memory cards, and over a third of those polled do not know how to store this data, potentially leading to millions of lost Christmas photos and videos.
And sales of gadgets may falter online, according to research by the Voice Commerce Group which found that 50 per cent of online shopping carts are abandoned due to lack of confidence or information.
The internet telephony firm predicts a greater take-up of VoIP technology by online retailers as they realise the need to offer customers direct contact with sales staff.
