- Okay Paul, although this wasn't directed to me, I can personally tell you how
- owning a 48SX has saved me LOTS & LOTS of hours over my previous 28S (and my
- 15C, and my 33E that didn't even have continuous memory!). If my battery dies,
- or I do something really stupid like resetting memory and not trying to recover
- memory, I simply hook up my 48 to my computer (yes, I too agree that computers
- are a marvelous tool capable of more than the 48) and do in approximately 3
- minutes what used to take literally hours to do. I have a total of about 96k
- in my 48 and thats a whole lot of keystrokes.
-
- As far as things I can do with my 48 (ie problems that make it nice -note I
- didn't say necessary) I've saved lots and lots of time doing such things as
- solving differential equations numerically, which programs are freely available
- on the net to do, and checking timing for parts of the command load that goes
- to the Hubble Space Telescope. I have plans for my 48 to make it an invaluable
- tool for an amatuer astronomer, sitting under a dark sky and wondering what
- the epoch 2000 coordinates of a star are, since he has it listed as epoch 1950,
- and his reference book is sitting on his desk miles away. There are unlimited
- possibilities for the 48. You just have to expand your horizons.
-
- And I agree with you that the average student doesn't need a 48, or maybe even
- a 42, that a computer will come in much more handy for such people. And I
- wouldn't dream of owning a 48 without a computer, cause you'd have to type in
- everything by hand (ughh). But I wouldn't dream of just settling for being
- an average student either.
