I wasn't able to attend the 21st Century Learning Conference in Hong Kong but thanks to my PLN I have been able to still participate and learn.
I found the video about why schools should move to a 1:1 programme posted by Chris Smith (@shamblesguru) to be really interesting. These are educators from schools in Hong Kong (HKIS, CIS and KGV) who have actually moved to a 1:1 programme. Their advice: communicate, talk about transforming the teaching and learning, create a culture of excitement, focus on the pedagogies, professional development, planning, resources, infrastructure and technical support and leadership. Invest in people and not the tools.
