- Hi again Paul,
-
- [Whenever I start reading this tired thread, the battle mix theme ("Welcome
- to the Pleasuredome") from Toys comes to mind... rather fitting...]

- Displays should be matched to what produces their video. If the HP-48
- could display more than 131x64 pixels, obviously the same LCD display
- wouldn't have been used. By the same token, using a 1280x1024 SVGA card
- with a 14" .52mm dot pitch monitor would be ludicrous.

- Ok, I hadn't considered mono monitors. If you're happy with it, fine...
- probably well over 90% of the PC buyers out there wouldn't be, though.

-
- It may well be useable, but what happens when it takes a 4 foot dive off of
- your desk?
-
- I guess I can't really argue that much about cheap PCs. All of the ones
- I've used have just felt cheap and slow to me. If you're happy with cheap
- PCs, fine... but I'd really like something like a Gateway 2000 if I were
- buyiing a PC. (HP produces a fine line of PCs, too, but they really are
- overpriced :-) )

-
- The HP-32S II is HP's lowest end RPN calculator (the even lower end ones
- use an algebraic entry system). It has around 30 variables, and 384 bytes
- of program memory.
-
- On both my 48 and 32, I use the built in solver to find solutions of
- equations. I only use the 32 for simple equations, though, because the one
- character variable name and non-plotting restriction often feels rather
- limiting. (And I've encountered some pretty wierd equations in my life,
- where it really does help to see what they look like.) On the other hand,
- the 32 "starts up" a lot faster than the 48, and I prefer to use it for
- things like adding long lists of numbers (checks, for instance).
-
- I don't know why I'd use a $15 Casio over my HP-32S II. :-) The 32
- does cost something like $50 or $60, though, and a $40 Casio can probably
- do more than it can. The use of RPN and the similarities in operation with
- my 48 make it worth the extra $$$ to me. (Actually.... do $40 Casios have
- solvers and integrators in them? They must, right?)
-
- There are still people in my math, physics, CS, and engineering classes who
- do use those $15 calculators, just like you say you did. They can do just
- as well in class as I can, but I do think that they spend more time doing
- algebraic manipulations and "number crunching" than I do.
