Laptops with unbreakable link;In brief
A pioneering American project may have come up with the answer. Rio Bravo Middle School, Texas has 94 per cent of its students living below the poverty line but all are equipped with portable computers. Using a wireless infrared network, students receive homework on screen, send e-mail and surf the internet at high speed. Their lap-tops, crucially, become unusable if they are not connected to the school network regularly. The only catch: it costs more than pound;1,300 per pupil.
