Notice I did not state the Ti-89 is the superior calculator,
Your (valid) point about market inertia aside, while you may have stated the 50g is superior in some ways, you damned it with faint praise, in my opinion.
I stated it is the calculator you should choose for the normal high end user that canít transition over to RPN (and most common calculator users canít or wonít, same difference).
Doesn't this assume that high school and college students are lunkheads incapable of learning anything? (Oh.. wait..)
Seriously, motivation aside, younger folks are far more capable of absorbing new techniques and knowledge. If you use mobile text, how well do you do at it? (I get by, but with a good mobile keyboard.) If you use Facebook, how well did you make the transition to Twitter? Did you find the transition from Myspace to Facebook easy or hard? Most young folks made both of those transitions, and will undoubtedly move on to whatever comes next. What's more, they still have and occasionally use the older accounts. Old farts like me tend to stick with Facebook.
Apart from the relative merits of RPN vs Algebraic, I think the difficulty of learning both is exaggerated for most young folks of reasonable intelligence.
If you canít read the screen of the Ti-89, Ti has the V-200 option available.
Granted, young eyes are going to have less difficulty with illegible displays than my older ones.
EE and ME pro are kinda nice perks that Ti has made available for free on the Ti-89 family and arenít officially available to the normal Hp50G user either.
TI can certainly afford to throw in more extras, given the volumes at which they sell their machines. Of course, to some extent, they need to do that because the underlying implementations lack features.
I could not in all honesty elaborate on those advantages to the normal user. That would mislead the normal (and not all that technically savvy) user to believe that the Hp 50G will solve his problems by the simple purchase of the calculator.
I take your point that TI's domination of the educational calculator market is a powerful argument for using their machines in high school, and to a lesser extent in college. But I think this statement ignores an important fact. People under 30 years of age use the Internet in ways many of us older folks simply don't get. I was talking to a lady friend in Facebook chat last night. We were both listening to the same shoutcast stream - offshore radio - playing "old fart" music from the 50s, 60s and 70s. I was identifying tunes and artists from memory and doing pretty well at it. But she was cleaning my plow by using google on the lyrics. She was back to me with the identities of obscure songs in seconds. (I mean less than five, typically.) The point is not that googling such things is hard, it's that this was her first thought when confronted with a game like this. She's 30, and says her 10 year old daughter puts her to shame.
So I think your dismissal of hpcalc.org isn't warranted. Any young person with a tiny bit of interest in an HP calculator will have instant access to that site, and the rich resources available for the 50g. Of course, "tiny bit of interest" is a key phrase here.
Hp50G SD card, this is a great plus if you are aware of hpcalc.org, however, many typical users never download anything onto their calculators unless it is games or the teacher distributes something in class. If the Teacher does distribute something in class, IT WILL be for a Ti.
See above as to hpcalc.org. You restate your main point that TI's market domination makes their machines a good choice for high school students. But I think your denigration of Internet resources here is just plain wrong.
75 (or 200) MHz processor, My Ti-89 has never really been slow, especially in comparison to an Hp 48G. So Hp corrected their problem, but the Ti-89 never had complaints among the typical user for lack of speed.
Straw man. You lead with a comparison between the 75Mhz processor of the 50g and that of the TI-89, then dismiss it on the basis of a comparison with the HP48. Then you basically say the TI-89 speed is good enough. Maybe, but you are jumping through hoops to avoid acknowledging a clear advantage for HP.
Hp 50G LCD Another good point, but the standard user of the Ti-89 is probably 20 years younger than me, anyway and if not, can most likely afford to upgrade to the V200.
Check. As above, young eyes do better with crappy displays. And since today's kids will be unlikely to continue squinting at any calculator after they leave school, the concern about eye damage is probably misplaced. :)
The Hp 50G clock, is a step backwards in comparison to the older clock in the Hp48G series and the newer Ti-89 now has a clock.
The verdict is still not in on the Hp50G keyboard quality, although I am inclined to believe it is a great keyboard and its layout is far superior to the Ti-89.
It has also been shown to be more durable than the 49g+ abomination. Point taken under advisement, but I think it's just here for rhetorical purposes. The 50g's keyboard may not last for 10 years, so we should make buying decisions on the assumption it won't. This denigrates the improved quality of HP's top of the line keyboards far more than is warranted, in my opinion.
Check, and check.
Lack of sound, lack of printer, lack of power connections, none of these features are really important to the typical calculator user.
The slide on cover for the Ti-89 is probably the smarter choice of protection for Tiís intended market. The Hp48Gii uses the same type of slide on cover. Students do not take care of their equipment nearly as well as older professionals as a general rule.
I suggest you re-read some of my review. 9 out of 10 students should buy the Ti-89 for their studies, plain and simple. I have seen too many reviews where the typical student who buys the Hp 50G ends up abandoning it and buying a Ti. My review is meant to help that student avoid that mistake. As stated earlier, the inertia of the market ie limited number of Hp50G users available to consult is very limited and therefore if you buy an Hp50G, you cannot get personal help from any professor or fellow students (unless your professor is Harold Climber!!)
OK, once again, your main point is valid. It's a hard pill for me to swallow that the far more powerful and elegant 50g or even the 39/40gs, are not appropriate choices for most high school students, but I think it's true. However dismissing resources for support that students will most definitely find, if they have an interest, is wrong.
