I can understand your point, but in my initial post I also mention that we use apple TV and that our VLE app only has a teacher version compatible with iOS. I should be clearer perhaps about this; teachers project their iPads on to the screen, rather than using a computer in some classrooms, especially members of staff who teach in multiple rooms. Our VLE is central to everything we do at school, so it is incredibly useful to be able to run this app on a compatible device. I am sure that a lot of the apps we use are available on android devices too, but not this one. Dictation and voice recording has also been used increasingly by staff at the moment, especially when all feedback is being given digitally. I will certainly look in to more low cost options, I just want to make sure I am not taking away any functionality that our staff have become accustomed to using. The idea of involving staff in the decision is essential I think, so I think this will be my next step. Thanks!
