Calculators vs. PDAs
Posted by Nick on 13 June 2002, 01:22 GMT

CNN has recently put out an article (discussion also on Slashdot) regarding the slow but definitely palpable convergence of graphing calculators and PDAs. Since TI has essentially cornered the graphing calculator market (others would be quick to debate that, but it's what I think), the article places major focus on their business strategy (FLASH on the 83+, Voyage 200, and so forth) and its relation to Palm's inclinations towards mathematical applications and suchandsuch. This is definitely worth mulling over and discussing. Go!

We can all agree TIs are better, I mean, there is an Internet Browser for the TI-83 and 83+! but sometimes I wish TI made EXPANSION SLOTS for the TI models that have risen since 1997, since PALM was founded then, and I think there were expansion slots back then. And also in hand-held models, and a 33-MHz processor, but in other terms, TI calculators are 100% CUSTOMIZABLE AND CHEAPER. I mean, you can learn to program, and make your own programs that would fufill a need, unlike the Palm, except for Palm programmers. Plus, you have tons of FREEWARE. Look how much archives the TIcalc.org has! and at $100 or so cheaper than the TI-83 Plus, heck. We should all get TIs instead of Palms

I forgot. TIs are better than HPs! (not to mention that TIs are not that overly high-priced)

33 mhz processor? So? 83+ SE has 15mhz, processor, thats more than enough for anything you could ever need to do on a calculator. Only reason for the 33mhz processor is so that they can make a lot of money selling you crappy Doom clones and stuff 8-\ and somewhere a little bit down, some guy brags about an "advanced match package" and yadda yadda yadda and SO WHAT!?!?! it probably cost him $30, and so did each of the games and blah blah blah....not to mention the palm and all his other stuff for it cost a total of AT LEAST FIVE TIMES what an 83+ SE does...

If I could pry a TI-83 Plus Sliver open, and if the processor wasn't overclocked, i bet that thing will go 2x faster or maybe even THREE, but remember, I think Palms use 16-bit processors so...

How do you pry a Sliver open??? That's a funny way of saying it.

How do you get your keys mixed up so much? Probably you created a custom keyboard layout and switched the keys around to confuse your annoying, foolish younger siblings.
Custom keyboard layouts will confuse anybody, especially if you have a PS2 connector that snoops keys before they get translated by the computer! (I have seen such a thing, and believe me, they are not pretty)

33 MHZ Processor? Are you that blind to the obvious? My Pocket PC is a year+ old and is a 166 MHZ. I know that there are brands out there with 266 MHZ+...

You're lame.

ok wtf man there are NO 266MHz processors YET
WHAT IN THE WORLD HAVE YOU BEEN READING?!

Sure, that's fast enough, but it probably doesn't have an MMU that's necessary for Win98.

SCREW YOU!
MY POCKET PC 2000 HAS 226 MHZ processor.
I CAN RuN LINUX ON IT
AND I DO

you wanna hear something cool?
two most disgusting computers in da house!
My elementary school has a 486SX based computer, 16MB of RAM and Windows 95 (the firsrt one no OSRs)
My friend Chris' computer is an old Gateway 2000. Pentium 75MHz (no MMX) 380MB HDD, only 16MB of HDD and no graphics cards!

Actually no, StrongARM processors are very different from Pentium-Class processors. So a 203MHz strongARM could run about ~75MHz and that wouldnt be enough to run WIndows 98, but Windows 3.1, 1.1, and 95? Yes

All listed below are categorized under Pocket PC Devices:

206 MHZ:

And a DOS Pocket PC exists:

*The ones thatl ook like laptops are actually smaller and thinner, and weigh a lot less than traditional laptops. I should know, I own one, and they are classified as pocket devices. (I own both a Pocket PC (handheld) and a Pocket Device (the smallish laptop).

(disgusted face)who would ever WANT a DOS Based Pocket-PC?!

It was an industrial Pocket PC. I suppose some do...

DOS IS MUCH MORE STABLE than WINDOWS!

Me! Where you can buy it? DOS is ideal for pocket device, there are millions of software applications, and you use keyboard instead those ugly mouse replacements. If I could buy pocket PC-286 compatible with 640K RAM and 2M of flash RAM for less than 250$ I would order it promptly. It is enough to be 12 MHz machine with CGA graphics.

I have seen such machine three years ago in Hanover, but I had not money to buy it, because I wanted to buy IOmega ZIP drive.

We can all agree DOS is virtually non-crashable.

and i would say that winxp is second (at least for pcs)

I would say Linux is second. I've never crashed Linux, yet I have crashed WinXP several times.

On second thought, I'd put Linux first, because I've easily crashed DOS (just try any misbehaving program/game; you see what I mean).

Even Linux is not unbreakable. I remember when I tried Sasteroids from Slackware 3.1, it crashed whole system (Micron Millenia Pentium 200, with 16 M RAM). If telnetd was not starterd, only power down helped.

Also, some programs under DOSEMU can do the very similar kind of crash.

However, the most dangerous can be faulty device drivers, because they are compiled inside kernel.

Actually, when speaking about uncrashable OS, the real question is: What does it mean uncrashable?

Possible answers:

a) No need to press reset at all
b) You need to press reset only if your application crashed, but not the OS
c) After powerdown system continues normaly
d) System can work for years without power off
e) Replacing system files caused minimal damage

Now, if you choose one of those critherias and if you compare different OS-es, you will receive different answers which one is the most uncrashable.

With MS DOS, or on TI calculator you need to press reset button quite often if your application is bad, but not in other cases.

With Linux, Windows 9x/NT/2000/XP you will rarely press reset button at all, but the causes of crash can be several, not only the program you have started.


On TI calculator you can not screw up operating system because it is in ROM (forget for the moment dirty methods of Julien M.). With DOS there are only 5 critical files, while on Linux and Windows there are about 200 critical files and therefore they are less prone to damage of system files.

Damn! My main machine is a 166 Mhz Pentium I! I run tigcc, vti, win98se, etc. and they go DECENTLY FAST on my machine! Imagine: TIGCC & VTI on a 600 Mhz palm thingy!

600MHz, is enough to run SImcity 3k!
