Our school completely changed to white boards a few years ago, and have recently installed three or four of these computerised 'smart boards'. They're quite good in some ways, like it can be used like a large TV screen for films and stuff, but mostly, the teachers don't get round to using them as they either can't, or don't have time to make the presentations and they tend to be a bit awkward to write on (bits keep getting deleted for some reason).
