Instead of offering a mechanical keyboard in blue units, which
entailed some manufacturing complications, we'll have it as an
optional on the usual green/white.

It's different enough that it's a separate model altogether (CL2 for
membrane, CL2A for mechanical kb) -- meaning it's different enough
that it requires separate certifications (yup, double up the cert
costs). This makes sense if you consider that CL2 can be certified as
a"children's product" thanks to the safer design of the kb.

We are doing some background work to improve the membrane kb --
mechanical engineering is hard and can't be rushed (not with good
results anyway). So it's hard to know whether it'll make the cut. Keep
your eyes open for C1 stage units -- :-)

cheers,

Thanks a lot for the explanation, I always find these "tiny" production, engineering, and certification details quite fascinating! :-)

Cheers,

Improvements to the membrane keyboard would be greatly welcomed. The
biggest problem that our teachers deal with are keyboards that have
been ripped out. Is there anything being done to reduce the
likelihood/impact of this?

Thanks,

I'll let Wad answer in detail, but there are some improvements
undergoing testing. Looks promising.
