One of our schools has purchased Dell netbooks without the accidental insurance option.  Online Dell shows that you can purchase this insurance as part of the configuration for $49/3 years (unless I misread that), but the best quote our sales person has give us after the fact is $161/3 years...not worth it according to administration, for a $360 computer.  I have done a single computer quote at Safeware.com at $130/3years and we will probably get a quote for all machines (around 140 total).  We've also explored "self insuring" by purchasing extra computers with funds generated by offering parents/guardians the option for insurance for a nominal fee ($50-75).
I'm curious, actually our administrators are very curious, about what other schools are doing for insurance...if computers are going home with students.
Appreciate any feedback!
