TI Still is - try finding an HP 'Scientific' calculator in the stores - slim pickings but there are still lots of good TI ones at excellent prices! I root for TI but like HP they have found it hard to stay at the forefront.
The one current HP that I still find worthy of its heritage is the near-immortal HP-12c Financial which celebrated its 30th birthday this year. I remember teaching evening classes to realtors and brokers on how to use this gem 20 years ago. Like the DC-3 and C-130, there are some items that are the acme of practicality and design and just keep going!
Whats her name Carly Fiorina destroyed HP.
They used to lead the world in scientific measurement.
Now its Agilent, and some of its good and some of it sucks.
I have an HP35s, which is pretty good, except for the PITA entry of digits A-F in hex mode.
In B-school, 20 years ago, the HP-12c equivalent that was suggested, if RPN wasn’t your forte, was the Sharp EL-733
