What would you say is the final model that "has it"? Besides my vintage HPs (HP15C, 2xHP16C, HP45) I also have the 50g and the modern 35S. For me, the 50g's lack of a proper ENTER key ruins it. I'm sort of on the lookout for a nice 48 series to replace it for that reason. The 35S at least has a proper ENTER. |

For me, at least, probably the combination of the 48GX and 42S. Both represent the end of the line of HP's traditional hardware engineering, which is such a significant part of using these devices. The software gaps between the 48GX and the later 49 can be made up by installing software into a 48, if that turns out to matter for you.
One of the more significant new parts of the 49 software is the "Meta Kernel", which was externally developed by Jean-Yves Avenard as a 48 extension. IIRC, Avenard ultimately wound up working for HP on their calculators, which I believe is how MetaKernal wound up as part of the core 49G ROM. IIRC, this was also a bit of a reconstitution of HP's calculator engineering effort, as the previous team had been disbanded a few years prior. (ie; William Wickes, who was heavily involved in the 41 and 28/48, wound up at some point working on video conferencing systems for HP.)
The reason I'm also including the 42S is that it's a lot more traditional in the way that it operates. If the 28/48/49/50 series feels like a small handheld computer with a custom programming language, the 42 feels more like an actual calculator (with a lot of capabilities).
