I’m not fully convinced of Mix, it does have its flaws, but I acknowledge it is in Beta and Microsoft are listening to user voices and opinions – Customer Feedback for Office Mix
A great resource regarding Microsoft Mix for PowerPoint… http://www.mixforteachers.com where this PDF guide can be found and a wealth of resources to highlight its abilities and to promote among colleagues. Such as how staff development might utilise it with “PC/VDU users” or “E&D training” or college wide development for the student body (and staff) such as can be demonstrated here!
