At MSJ the cost of breakage was about 10% cost of the program.  Which meant
that more than 10% of the computers broke, but the cost to fix those came
to be about 10%.   Broken screens were the largest culprit.   Out of 3
years I only had 2 that needed complete replacement due to mis-use, nothing

I did learn a few things.
1. Don't expect a sub-$300 device to last 4 years.   At FHU we are going
1:1 next year and I plan to do a 2 year fair market value lease.  This
allows us to replace the devices every 2 years, and not have to pay the
full cost of the device.
3. Loose hinges will destroy a device!!!!!!  This started on Year 2, but
the hinges started loosing.   If the plastic mount breaks because the
screws were loose the device is instantly turned into a parts machine.
