Convenience or health?

The present wired (i.e. non-wi-fi) computer system at [name of school], installed with the new building, is state-of-the-art. If there are any benefits to education of adding specifically wi-fi computers—I know of none—they can only be marginal. One commentator remarks:

"With dLAN systems13 and ordinary CAT5/6 wired networks offering better stability, bandwidth and security, there is simply no need for most homes, organisations and schools to switch to wireless networks, apart from the savings of the slight inconvenience in cables." 14

The choice is not, then, between health and education, but between health and convenience. Which is more important: a slight increase in convenience, or the health of our children?
