Of numerous _really cheap_ old calculators with rubber keyboards,
my number of key failures remains zero, as it does with
(more expensive) Sharp Wizards (also rubber keyboards, still in use)
and a fine cell phone costing me 1/3 the price of an HP50G.
It's been ages since I've had anything branded "HP"
that isn't manufactured by an OEM of "junk" quality,
with Kinpo (the OEM for these calculators) being the worst ever.
Picking such an OEM for an otherwise high quality intellectual concept
does not seem to have been management's finest hour.
Take heart, however -- they might be able to grind up the otherwise ill chosen plastic
from an overrun of junked calculator keyboards, and enrich powdered milk with it.
