As a professional swimming coach when working with disabled swimmers I was taught to play to a person's strengths.
When AKH talks about the inequalities of access, on the one hand she mentions the affordances of such devices on the other ... we find a way to play to their strengths - is it not these developments that drive advances?
Woman needing and wanting to study favour learning via a mobile device (smart-phone or more likely a standard mobile) as it can just look as if they are on the phone. There are cultures where learning is liberation and where liberation is not something the men want 'their' women to have.
I wonder how many others can now take their mobile device into a 'space of their own' (to paraphrase Virginia Woolf), so that they can Rita-like (as in 'Educating Rita) 'improve' themselves.
