I feel that you should not think of the 38G as an enhancement over the 41. The 38G is really a schoolboy's crutch, not an engineering programmable. That is not to say that one could not figure out a way to program it--it is just that it really is not worth the trouble! The 41 is the last large-memory I-O capable RPN Keystroke Programmable(to like a compter or card reader etc).
The 48G, 49G+ and 48GX are RPL, not RPN, as is the 49G. This is an "enhanced" high level language, and is reverse polish with a stack, but a whole new ball game really. You can also get HP41 emulators that run on the 48G series (generally 48gX) and even an HP-produced 41 emulator, with keyboard overlays, which runs on the 48SX (a discuntinued model easily obtained in good condition). Expanded memory for the 48 series can be obtained at reasonable cost from some german makers--HP no longer makes memory expansion. I do not know the technical details of the 41 emulators or the memory required--but I know there are a number of different choices--in fact I have been contemplating that route myself.......but it is too much for me to figure out just now...
If you want to see just how enthusiastic some people are about the 48 and 49 series, just go to comp.sys.hp48 and to hpcalc.org. But if you are an engineer, not a computer geek, you will probably be overwhelmed....:-) Ther eis also 38G stuff at www.hpcalc.org.
