They certainly aren't. Myddelton College, the first Microsoft school in north Wales, is currently benefiting from 5G wireless technology, which the rest of the UK won't start seeing until 2020. So, they're well ahead. College pupils there are working on tablets allowing real-time interaction with teachers for lessons and marking. The school estimates it will save around £100,000 a year on printing paper and pens. So we have got test-beds around Wales, actually, looking at different systems. There are complex ways of financing those, but they are spread across Wales, but deliberately so, and we're very keen on looking to see that we have test-beds in very rural areas, in semi-rural areas, in city and rural areas, and so on, because we know that the technology will have different problems and issues and different benefits in all of those areas. So, we've been very keen to make sure that we have a spread.
