Indeed Carolyn, welcome to MR and for sure keep us posted on your project, especially in how the kids like the Kindles and how the Kindles stand up to the ...ahem...abuses which will inevitably be thrown their way by those little boys and girls. May be very useful real-world examples for those more clumsy adults among us.
Sounds great!
EDIT: Carolyn, think about making a new thread for your K3 project. I would think that the subject would be of some interest to people around here.
