The right cursor key under swap is x<>Y without needing the shift key. But last entry must be entered onto stack before using it because it acts as a cursor key while entering data.  It works from the computer right cursor key also

If you are not yet "spoiled" by the real HP48, than the HP50g is probably acceptable for you. Functionwise and pricewise actually it is a lot better compared to  the old 48
(If remember correctly I paid 500 DM for the 48GX, which would now be close to 250€ and for the 48SX I paid at least double of that price (with 128kB RAM card, HP solve equation Lib and serial interface kit)).

The main point I am disappointed with it, is the poor build quality compared to 48 Series, the look and feel and the many changes I struggle with. I just instead use my HP48GX, because I am faster. But if my 48GX brakes like my 48SX just did, I either have to get used to it or will go for the TI-nspire CX CAS.

You can buy this book if go for the TI-nspire...
Gives you a speedy way into the best calculator there is ..  :)



But the math with TI-nspire books by Brendan Keely is a joy to read and use.. highly recomended!!
The best there is..

Besides that, a spreadsheet does not have a solver. For instance my hp-48GX app has one formula for the thompson resonance formula. And using the solver i can get frequency, L or C. In a spreadsheet I need 3 formulas for that.

Toch wel hoor.

Excel has a solver although I have not used it myself.

Have you used an HP calculator? The Nspire is a huge toy in comparison. The market reception is so poor that they are re-designing it http://tech.slashdot.org/story/12/11/11/1819236/color-screen-ti-84-plus-calculator-leaked

Sadly, they are re-designing it to look like the Casio FX-CG20

For those more interested in proper tools rather than toys, you can now get rip-off sorry tribute emulations. Unusually, they are from Switzerland not China, and are credit card sized: http://www.rpn-calc.ch/



I wonder if Dave has seen these, they seem similar to his uCalc project.
