One of our worries was having the ability to use Promethean software with Linux. All the teachers in our school are familiar with ActivPrimary and keeping it is a fundamental requirment for us.
Further research in this area prompted a few clear signs that development is under way for new platforms. Thankfully for us, Promethean are following Smart on this one.
We have been given the chance to evaluate Promethean's Linux offernings. We plan to take up those offerings soon. As yet we are unsure as to what they have on offer, but I would imagine it's just the driver software for the board and not the ActivePrimary software.
