Students will be able to take advantage of a £99 laptop from Elonex from the end of this month.
The One laptop will be launched at The Education Show, which takes place from 28 February to 1 March in Birmingham.
The laptop, which will run on Linux, will include a 7in screen, 1GB flash-based hard drive, wireless access and a rubbberised keyboard, which can be detached to create a tablet PC. The laptop is expected to offer a three-hour battery life and will weigh just less than 1kg.
"The One removes the cost barrier that has prevented the one-laptop-per-person, large-scale uptake of computers in the education system that has for so long been just a pipe-dream. Investment in digital technology is paramount to help the next generation achieve their full potential," said Sam Goult, marketing manager at Elonex.
It is expected that a digital USB wristband offering up to 8GB of memory and a version of the laptop with a Bluetooth connection will be available as optional extras.
