Thanks for the comments, everyone. Push/pop commands with some programming could be a partial work-around. I think Tim hit it on the head by saying task switching, which is what I was looking for.
yes, it is easy to learn and operate. The build quality is same as 50g. I was able to show the concept of graphs to my 7 yrs daughter. ( she was asking for a graphing calculator afterwards :)). It also helped me understand the capability and expandability of 50g because I would go back and try to do the same thing on 50g.
I do think that everyone discounts the 39/40 though - especially here since they are algebraic only. They are very simple to operate, and even simpler to explain how to use, but that simplicity definitely puts of those wanting to do things more than 1 or 2 ways that are supported. The 50g shines in its flexibility.
Remove those limitations (such as give it units, more flexibility in programming, and some more customization) and I think more people would be willing to give it a shot.
within a week of use, i don't have a strong feeling of anything missing (for its purpose). Units would be nice and also if one could enter multi-character variables in solver. however, after using 50g and 40gs, I find there is a fine line between keeping it simple and complicated. For my use, I would keep 40gs as is (=cessna) and use the 50g (=fighter jet + airbus). :)
I haven't started programming yet. the views reminded me the event-driven programming. It looks like it is possible to add pictures to applets, which will be nice. I'm thinking about making tools for calculating pcb trace impedances. Also, when I calculate the impedance of a cap or inductor, I want to see a plot of the impedance vs freq with cursor at the entered freq (maybe this is the split view.)
Now if i can figure out how to overclock this calc, that'll be cool :)
