1st I thought that it would be great for teachers that teach like post labor hours, those kind of education, workshops etc and it's a little cool device to have on classes, instead of a laptop and a projector, that always is a pain to set and to view etc etc, but then I went to see the price and it's expensive, on an optic of only having this for that kind of work it's good, it's tiny, you can easily configure it, but as I said the cost is a drawback.
