TouchScreens / IWB Replacement
We are looking to purchase 4 touchscreen 65" devices in a new block for maths, they previously had 9 year old 'Interactive Education' Boards which have seen enough action. We are looking at the follow models has anybody used them or thinking of going down the same route? The rooms have no AV at all so weighing up the difference between a projector install + interactive board V Touchscreen TV.
