Hi Everyone,
Well, I guess we can at least all take comfort in the fact that this is,
when everything is said & done, a "...throw away" society...
Sooner or later (probably sooner) these incidious devices will break down, &
since nobody fixes things anymore, it'll be into the landfill site with
them, & onto to the next latest-and-greatest-must-have consumer techno
toy...
Hopefully the next generation of "toy" will be more RFI-friendly!
