Being totally selfish, whilst also donning my fave rose tinted glasses, those HP pocket computers led to RPL,and HP certainly knew their market on that front (if we forget the 28C ever existed with its piffling 1-2kb of user program.RAM).
In any event, it wasn't that HP deliberately decided to limit the amount of memory available in the HP-28C, it was more that they decided to build it at all. The HP-28C became a pivotal stepping stone for the models that came after it.
I agree with everything you say, I was being flippant.

[*]INTEGER operations being slower than REAL ones is counterintuitive and frankly appalling, to say the least.
And indeed, this oversight extends into the RPL series as well. User access to the system (unsigned 20-bit) integer type would make many programs run much faster.
