It will be interesting to see how this plays out in the next few years. There are those who dismiss Chromebooks but at $200, they're practically disposable and bullet proof for little kids. My five year constantly drops and abuses his Chromebook and we don't even worry about it to much. Most of the school curriculum are web based and unfortunately, many of them still use Adobe Flash so he turns to his Chromebook quite a bit over his iOS device.
In the meantime, Microsoft appoints a new CEO with a strong cloud infrastructure background. There is hope Satya Nadella has some sort of education strategy in place. Today's children are future customers for any of the tech giants.
Here is case study of how a Kentucky private school deployed chromebooks for their middleschoolers. Link: http://www.techrepublic.com/article/private-schools-chromebook-program-explains-why-googles-laptops-have-captured-nearly-20-of-the-educational-market/
The most telling quote is this:
"While cost savings can be made on the cost of the hardware alone, the majority of the cost savings originate from savings made from infrastructure and device management.
I think that is what really matters. The infrastructure cost and ease-of-management.
