I thought Laptop etc were not Li-On but NIMh instead??
Li-On seems to more reliable and getting better all the time.
Who says its the kids that don't want the noise and its the "adults" themselves ie Headmaster, teacher.
Remember the kids are our future that Old people (adults again) have messed up. :wink:
Also remember the kids of today are picking our/your retirement home when they have grown up (oh no adults again). :laughing:
As for the battery impact the only problem I see is it take good servicing away from dealers etc
