• I'm sure the 41cx's text editor could be vastly improved;
• string manipulation and HPIL I/O might be expanded;
  

Fully agree

That will have to be seen ...
Assuming we have something like a pageable HePaX memory module of 16KWord per page (= 32KB/Page non-optimized)
and we take a small (by today standard) 32 GB SD memory card then we have a system with 1 Mega pages to manage!

+1
With only two wires (not counting VDDs), I think I²C is better adapted to the HP-41 than the SPI who need a slave select (SS) for each peripheral on the bus.
