If, for any reason, you plan to spend more than $7 on a calculator, the TI-89 is the only calculator on the market worth considering. <-- (note the period)

After many years with TI-86's, 83's, 81's, colorful Casio's, and even HP's (which have to be used upside down!), Trust me when I tell you they might as well be abacuses compared to the 89.

Anyway, great deal and great deal on the USB cable also. I just got one of these cables free from Office Depot to replace my 25 pin(!) serial cable. According to TI, the USB cable requires Win2K or XP but the driver only works with Win95 (?). I think they claim that the worst of both worlds (WinME) supports both the cable and driver -- as if! So I bypassed all the warnings on ti.com and installed the latest driver on my XP Pro system without incident.

Not so, the TI-92+ is awesome if you are willing to use a different style calculator. Initially I thought it looked kinda big, but once I acutally got mine and started to use it, I loved it. Keep in mind that the TI-92+ == TI-89 + An extra feature or two (I think the geometry editor isn't on the 89). The actual usage of the calculator looks and works the same, you just have a slightly larger screen to work with and some extra buttons, a keyboard, etc. As well, I believe the TI-92+ has extra memory and a more powerful processor. I think the TI-92 was kinda fudged, but the TI-92+ release was awesome. Not to mention that I picked up my TI-92+ for $150 and free shipping from NewEgg almost 2 years ago, back when places like CC, BB, and OM/OD were trying to sell just the TI-89 for more than $150. That was a sweet deal.

Well, the 92 is more of a hybrid -- a cross between a calculator and a typewriter. The TI-92 is the most powerful babe repellent on the market, and with it's unprecedented size and weight, it's tough to conceal from the chicks.
But being the functional equivalent of an 89 and then some, it too is a great contraption.

I believe that the Ti - 89 has the same processor as the Ti 92 plus. The only difference between the two is a larger memory in the Ti 89. The software like Cabri Geometry sketchpad is useless because it is pretty hard to use (I tried it out on my teachers Ti 92) and there are probably freeware out there that are much better. The Ti 89 are also allowed on SATs etc....BTW the Ti 92 plus seems to be no longer endorsed as much by TI. If you have a look on their website they have the Ti 89 and the Voyage 200 on their front page. It seems they are promoting the 89 for the more conservative look and SAT usage etc while the Voyage replaces the 92 plus. IMO the 89 is good enough and for the price it is an absolute steal (I got mine for $169)

Bah.. HP 48GX all the way. Ti-89 might nicer to look at with all those fancy menus, but the HP is quicker to use.

agreed. i have a 49g, and my brother has a 89. with my 49, it is so much easier to enter in a equation using the equation editor than it is just typing it in with the many parentheses on the 89. also the 49g can simplify ;)

You are just wrong with the above statements. IMO the HP49 is WAY better than anything that TI makes, including the TI-92 because of three letters: RPN. Once you've gone RPN you'll never go back. And if you really think the HP49 is an abacus, there are thousands of people who will disagree with you, HP is the standard of the scientific and engineering communities the same way TI owns grade school. I could say something like "oh, Mr. expert genius ninth grader thinks he knows something about calculators" but I won't because I don't want to start a holy war. Just use whatever you like, but don't discount something just because you are unfamiliar with it.

sendtrash: Everything! Look at the wealth of amazing applications on Ticalc.org.

dancingpig: You have clearly never used a TI-89. When you do finally try one, be careful not to hurt your forehead by smacking it too hard in disbelief. The urban myth that using an HP upside down in a vacuum is somehow faster than a TI-89 is bizarre and completely unfounded. HP users simply justify the virtually incomprehensible interface with the cult belief that adding 5+5 on a regular calculator requires 21 keystrokes. To add 5+5 on an HP you type "+", "9", "enter", "2" and the screen reads "10" but gives you no indication of what you entered or what the calculator did. On a TI you'd type "5", "+", "5", "enter" and the screen reads "5 + 5 = 10".

CrazySharks: I haven't used the 49G but I understand that it is a mirror image of the TI-89. Although the HP is significantly more expensive, it can perform all of the functions of a TI so long as you hold it up to a mirror. RPN? Sheesh! Why do you want to reverse engineer an equation and try to figure out the correct way to enter it into the calculator? Just type it into your TI exactly as it reads on paper. I'm an aerospace senior and have studied in two schools in two states and never seen more than maybe one lone major switcher using an HP. I guess it's a regional thing but boy am I glad I don't go to a school that uses HP's!

pecel: Don't waste your money.

Just use whatever you like, but don't discount something just because you are unfamiliar with it.

TI89's can also do RPN with a downloaded program... search around http://www.ticalc.org for it. The biggest advantage of the TI89 over the HP calcs is the huge amount of software freely available for the TI89. When I was taking my electrical engineering classes, I downloaded a program that was very similar to PSPICE (circuit analysis program). I just inputted a circuit, and it gave me all of the currents, voltages at any element with lettered variables still in place.... and also i(t)= or v(t)= formulas for currents and voltages for AC circuits... such a crazy program... and so much more I never learned to use (if you're wondering... the program is called Symbulator). Needless to say, I totally owned on the final -- which just so happened to be a multiple choice test where we didn't have to show work.... hehehe ;-) There were also other programs that I found that did laplace transforms and inverse laplace transforms... very useful for EE classes on systems and signals. But yah... if you plan on taking advanced calculus or engineering courses... this calculator will be your hero! =)


For those of you capping on RPN... don't knock it until you've tried it. =) Even though it's a little ackward to learn at first, you'll start to see how useful it is when you have extremely complex fractions in fractions in fractions, or anything else with a lot of parenthesis. When you enter it in the regular way you have to balance the parenthesis and you can easily screw it up and misplace one and screw up your whole equation. When you do things the RPN way (postfix notation for you CS people ;-) ) the parenthesis are automatically taken care of.... it's in the nature of the postfix notation... well... that's not entirely true... it's not automatic... it's just that your brain is now acting as a buffer to hold the parenthesis... but it's so natural that you don't realize it. Kinda cool for very complex equations.

just so this doesnt get too OT, $105 for the ti-89 is an EXCELLENT price. if you need/want a graphing calc, this is an deal to jump on, no matter the comparison between the 49g and the 89. both will get you to roughly the same place, just a difference in method and how long it takes.

the hp isnt significantly more expensive. back when i was getting mine (last dec), the 49g with the computer cable @buy.com was $150 and the Ti-89 without the cable was ~$120 with the cable costing maybe $20. So they are both basically the same price.

re RPN, i must admit that i do not enter equations using the stack; i use the equation writer. i feel that it is much more intuitive and easier to discover any mistakes in your input becuase as you enter your equation, you can see exactly how it looks like (in textbook form).

i really dont like how you have to open and close so many () with the 89 when you are entering an equation. you have to remember how many you have opened, and you have to close them all at the end. pain if you ask me. it is also faster on many things (less buttons to push). for example, if you want the square root of say 20, in RPN, you would type [2][0] and then hit the [square root]. gives you answer in 3 button presses. on the ti-89, you would have to do [2][0][^][(][1][/][2][)]. 8 button presses. same thing with taking the sin/cos/tan of an angle. you have the extra [2nd] and [)] to press. on the 49g, all you need is the [angle] and then the [function]. as little as 2 buttons to push, the 89 needs 2 more.

RPN isnt hard to figure out, took me less than 5 mins to convert, and now i have trouble using a regular calculator :p. anyways, there is the regular algebraic mode availible in the 49g options that mimics the 89's operations.

what was this program call and it's available @ ti.org?

is there a website that show me how to use rpn?

i have both the ti-89 and hp 49g, and i want to learn to take advantage of the RPN and dont feel like put a long equation in the 89 and forget the open and close ().

I bought the ti89 the first day it came out and I love it.
lots of software out there and is probably the last calc you will ever need.

i paid $160 4 years ago. this is a nice price.

Yes im trying to get this back on topic.

Btw lots of games for TIs - eat that HP losers! (doh)

If you want games, get a Gameboy.

I don't like using HPs either, but arguing about which is better is pointless. Fact is this is a good price for a powerful calculator. Snatch it up if you need one.

first post says SoCal clearance. Have we gotten any confirmations that this is happening elsewhere? It has been my plan to pass my TI-86 down to my brother soon and grab a TI-89. At this price, it is an amazing deal because most stores are still selling it for $150+.

my local target(salisbury, md) had them on clearance for 127 a few days ago. Checking today though.

EDIT: bought it today for 105 - employee discount (total < 100). I guess its a nation wide clearance since their discontinuing it from all their stores.

They were out of the link cables though. Anybody know a good place to pick one up?

It's still $150 at the Redmond, WA store. I had them do a price check on the register to make sure. The Graph Link is on clearance though for $13.

Actually I have used a T-89. I bought one about 6 months ago and sold it to a friend because I do not like it. It is easier to integrate and differentiate with the TI-89 than on the HP48GX, but the stack on the HP makes it significantly faster for me to use. It has a better solver and equation library than the 89, and the module upgrades make it limitless.

Krazykilluh is correct. The HP is the most widely used and respected calculator for engineers, while TI rules grade school. The majority of people that I know who use the 89 use it because they can cheat easily with it. Take the calculator away from 75% of the people who use a 89 and they cannot tell you what the integral of cosine is. They cannot do the math themselves, so they rely on the calculator, and when it comes to a test, 90% of 89 users at my school have connected their 89 to their computer and type in notepad reminders on how to do problems.

Now, the TI Voyager looks pretty damn sweet. I might pick on of those up to play around with it when I graduate in May.

Let the flames begin.
