I've got two fairly recent LCD calculators - a Casio fx-82SX "FRACTION" and
a Sharp EL-531VH "Advanced DAL".

My Casio has most of those, except x ROOT y. The Sharp does everything you
mentioned, but the display contrast is abysmal. Look at it straight-on and
you can barely see anything; look at the display from a 35-degree angle and
you can actually see what it's up to.
I've got a Commodore MM3MW LED calculator - made in the late 70s FWICT. It's
a shame no-one seems to make LED calculators anymore - I could live with the
short time between recharges, but I guess most other people couldn't be
bothered (the Commodore has gone a fair few weeks on a single set of 750mAh
NiMH cells).
Heck, my mobile phone needs recharging every few days, charging a calculator
at the same time wouldn't be a big deal.
Later.
