I suppose I can sort of understand the lure of old-time red LED 7-segment displays; but I sure don't want to have to charge my calc every night. Reflective LCDs (the kind that are optimized for using ambient light only, and produce no light on their own) were a godsend, and it was so nice to be able to even years without thinking about my batteries.

That's true, but for the old Classics I think the LED still reigns supreme.

I had the MultiCalc running 24/7 on a 3.7V LiPo battery with 50% of the LED display on. Still working fine after 7 days with plenty left in the battery.

cheers
