Choose between an interactive touchscreen and a durable whiteboard assuming one has simply replaced the other, and a classroom can end up with technology that adds cost without adding much to how daily teaching actually happens. The two serve different needs, and a durable whiteboard often keeps doing the job a touchscreen was never meant to replace. Compare them on what a classroom actually needs, not on which one is newer, and the choice matches the teaching it needs to support. Neither tool makes the other obsolete — most classrooms end up needing both, just used for different parts of the lesson. Ask what proportion of the school day each tool would actually be used for before committing budget to either one.
