The short answer: Only if your teachers already have and know how to use laptops and projection devices (LCD projector, good sized TV, etc.) If you have not already provided the afore-mentioned equipment and training, there's a good chance those Smart Boards will end up looking like a real expensive overheads. More on this subject later.
Remember: Ready, FIRE, Aim! is not a good technique to use in considering tech purchases. More than one school I know of went out and bought Smart Boards not realizing they also needed to buy projectors!!
