As a matter of fact the addition of CAS has brought a suboptimal keyboard layout: the useless SYMB and X keys were added at the expenses of Enter key, reduced in size a located in the wrong place. Not to mention the upward shift of operator keys, just to make space for Enter.
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....
