Furthermore the addition of CAS changed the menus and made them confused.
I can ignore Cas, but not the it's consequences.
In conclusion, of course IMHO, the addition of Cas to the 48 series gave birth to a 48-50 which is less usable for some categories of professionals.

Just two words about equation library. I started having one in 1991 with my 48sx. Never used in 27 years except the MES and the periodic table....

I believe that the best place for ENTER of 2 key size is to be mid calc on left size exactly like the hp48gx. I dont know why. it looks natural to me.

thank you for the video of M. Prof. Feynmann.

I would be interested to know who first realized the cas system for hp. that was really early.... is the cas on hp prime much much better

It is simply a matter of what you get used to. The ENTER key should be on the same side as the operations + - * /. We are used to the left as it is what we got used to. HP-42 / 48 ... put the shift function keys and the like on the left .... Once you use a calculator it becomes second nature.. it is only in transition or if you use multiple calcs (ie collectors) does it become an issue...
