Yes, I agree the RPN is more elegant. But if yourāre just trying to punch in the long expression that youāve just derived, sometimes itās nicer not to have to dive down to find the deepest parenthetical clause.
RPN people think inside-out.

Yep! Mineās the HP 35s Scientific. (Had an older one around here somewhereā¦probably up in the craft room.)
Thatās quite a collection!

My wife bought a 20S in college and thatās the calculator I reach for. I like using it more than the more convenient one on my phone.

speaking of the calculator on smartphonesā¦ Did you guys know, that the smartphone calculator does not work well when you try to dial phone numbers with it? I canāt even blame that on being old, Iām only 40!

Hahahaa!!
No, I had actually dialed the phone number to the conference call line at workā¦ and sat there waiting for everyone else to join the call. I didnt realize I had used the calculator app until they called me direct to see if I was going to join the call. LOL!

I know weāre a small minority, but donāt forget about your international customers.
Bit hard to ship you the unit from Oz to replace a tube

I scanned and did not see this asked, so pardon if itās been brought up already:
Does the shipping cost include someone who knows what they are doing coming to my place and packaging it? Do we have to keep the crate it is shipped in?

Postfix notation but I donāt think RPN is rude. It is the reverse of prefix notation which was called Polish notation because it was invented by a Pole.

Assume the first question was tongue in cheek. But no. And itās a cardboard shipping box. So yes.
I still have my TI-89 from college. I had an 83 in high school I think. Lost my 89 when we moved from CA to WA, but thankfully when we moved again I found it! I still use it daily.
Yes, I realize it isnāt āoldā like these other ones, but for me, its a piece of tech that has lasted far longer than any other. Iāve had it sinceā¦ 1997 I thinkā¦ so 20 years.

Just a few years earlier, the TI-59 was life changing for me. Programmable (in essentially machine language), docked to a printer, stored programs on magnetic cards. My first āpersonal computer.ā I programmed the entire simplex algorithm for linear programming on one magnetic card.
Of course it was enormous. Those four foot long memory cards and three foot wide printouts really took up a lot of storage space.
