In a survey of more than 1,000 people, consumer website which.co.uk found the mobile phone was the most popular life-changing gadget, named by almost a quarter of people surveyed and 42 per cent of the 16 to 24 age group.

In second place came the laptop, followed by the MP3 player.

The foot spa was named the most useless gadget, with the bread maker close behind.

Jess Ross, editor of which.co.uk, said: "Forget games consoles and TVs, we've found that the mobile phone is the gadget that people say has changed their life.

"As the popularity of the iPhone has shown, the multi-functional mobile is worth queuing around the block for!"
