I believe the crux of the argument is:
Is 1:1 where we are headed?
And my thoughts are, Yes
Once we can agree on this then we can start to consider the underlying issues that have been debated and discussed by educators in online forums.
1. - Who pays (BYOD? School? Government? Corporate?)
2. - Will 1:1 create more eWaste and how can we responsibly manage it?

It is important to note that if managed properly 1:1 could actually reduce the amount of devices we have. For example as a worker I had a computer at home and a computer at work.
As a teacher in the Tela laptop scheme I now have a computer that travels with me to school and back. Surely we can create a system where children are doing the same thing? Then we will not require as many 'classroom computers', 'computer suites', or 'COWS'.
School computers lie dormant at night. Home computers lay dormant during the day...
3. - Will 1:1 destroy group learning pedagogy?
This is of course up to the individual educator. I believe, however, that I would continue to use Self Organised Learning GROUPS even in a 1:1 setting. The beauty of 1:1 is that learners can continue to contribute to a group's learning - even when they are not physically present.

4. - Who should we be buying our products from (from an ethical, sweatshop point of view)?
This is a question for ALL of our consumer choices and should not be used as a barrier to 1:1. If you know me, you know that the children I teach do learn about such issues. We have questioned the origins of our sports gear, clothes, computers, toys, mobile devices, carpet, furniture, chocolate, pencils, school uniforms ....
I will not accept that children's learning should be compromised by an ethical debate. Not when they are trudging to school in sweatshop shoes, wearing sweatshop uniforms, kicking soccerballs and being rewarded with chocolate produced from child labour. Our children need to learn about it and take action where they can. Isolating our children from these very issues by the banning of ICT equipment in schools is NOT the answer!

And that's my two cents...
