Hello, I want to clarify a few things regarding SmartBoard use and SmartNotebook software.
SmartBoard functionality can be used with any computer and program connected to it. The drivers that offer the touch and interactive functions are available outside of the need for specific software.
SmartNotebook is simply software, in which, one can create curriculum that is compatible with SmartBoards and other interactive products such as the BrightLink projector.
You do not need a SmartBoard to use SmartNotebook and you do not need SmartNotebook to use SmartBoards.
The old (no-cost) Smart Notebook license is not supported any more and is not compatible with Windows 10. They have moved to a yearly subscription based model at a cost of around $40/license/year.
If you do not have curriculum built in SmartNotebook, then you do not need it.
