Most of us have mobile phones, including school children, and now it seems they could actually help with children's education.
Research carried out by one of our universities suggests mobile phone technology can boost learning.
Our Education Correspondent Peter Bearne has this special report.
Drivers using their mobiles behind the wheel were told today to stop, before they kill someone. The message came from police who started a special operation to crack down on the habit.
They patrolled in Yeovil and along the A303 and caught a number of drivers.
Here's our Somerset correspondent David Woodland.
Figures obtained from the police by ITV News West Country reveal that:
Motorists are four times more likely to crash when using a mobile
phone. Reaction times are around 50% slower than normal
More than a million drivers have been convicted of using a mobile behind the wheel in the past ten years
Drivers in Somerset, using hand held mobile phones while at the wheel, are being targeted today.
Patrols will be out on the county's roads highlighting the dangers, and catching offenders.
It follows similar action in other parts of the west country.
The crackdown has been organised by Somerset County Council's Road Safety Team and Avon and Somerset Police.
It has been illegal to use a hand held phone while at the wheel since 2007, but many drivers continue to break the law.
