Hi Ros, I've been working on a similar document for various tools today and was going to give you a shout, so cheers for sharing! To clarify the wireless issues, the main issue is the amount of simultaneously connected devices catered for rather than the bandwidth being used, which theoretically would be the case with any BYOD stuff. Increased wireless points planned in lecture theatres by the end of the summer should hopefully eliminate, or at least vastly reduce, this issue.
To me what I've seen of RW, it does what it does very well (and probably more elegantly than LT), but LT does a lot more in terms of what students can do with it - polling is just one part alongside note-taking and question-asking. It's also worth noting too that if/when we get the integration into Echo360 it'll be really interesting to see how the two meld, and how useful students find that (potentially being able to watch the lecture back alongside their own notes, annotations and questions). On the flipside, obviously some departments already have Turning Point heavily embedded into their teaching.
