<p>Price is actually the same for both TI-89s, 150 buckaroos.</p>
<p>I was looking at Dru2k5's post and realized that i've never seen someone with a Ti-84 in my life.
<em>goes to Ti's website</em></p>
<p>On all my tests we weren't allowed to use a graphing calc. It's really not that bad.</p>
<p>But I have heard calc is so difficult and even really, really smart people (which I am not) sometimes get C's. Any way I can really improve my chances of getting a good grade? Would summer work from a review book give me a nice head start?</p>
<p>Def get a 89. Don't listen to these people who say you won't learn as much - you will. It will save you ENDLESS abouts of time doing algebra and stuff like that. 83 is OUTDATED. Get the 89.</p>
<p>The 89 is 100% worth it. </p>
<p>To avoid reliance, I learn to do things by hand first, and then use the calculator for most of the homework/tests.</p>
<p>If you want to save money but still have a very powerful and nice calculator, then purchase the TI-83+.</p>
<p>If you want to be a poser, no offense to those who have these, though, then purchase the TI-84+.</p>
<p>If you want to be L337, then get the TI-89+.</p>
<p>Of the three, the TI-89+ is by far the most powerful. It has features built-in the other two can only dream about.</p>
<p>There is a caveat. Some professors are wary of its power; thtey will not let you use it on their exams.</p>
<p>isnt there a Ti-92 out there?</p>
<p>yes but it has a QWERTY keypad which is a DQs it from most standardized test</p>
<p>isnt it better than the ti-89 though?</p>
<p>Nah, not really..my math teacher says the only difference is the keyboard.</p>
<p>TI 92 and TI 89 are the same calculator underneath the keyboard. Programs written for each are interchangable.</p>
<p>i actually much prefer the ti84+ over the ti83+...the USB compatibility is convienent. not to mention it has a much more comfortable feel because of its curved case. it is freaking sturdy too..i dropped my ti84+ from a three-story building onto concrete and it still worked.</p>
<p>"i dropped my ti84+ from a three-story building onto concrete and it still worked."</p>
<p>why would u do that? lol</p>
<p>science experiment?</p>
<p>
<p>If you want to be L337, then get the TI-89+.
</p>
<p>Now, I don't own a TI-84+, but ***? A TI-84+ is just the replacement for the TI-83+, just like the TI-83+ replaced its predecessor and so forth. I think the only poser here is the person saying L337.</p>
<p>Ti-89 is banned from some testing environments also. I believe it is not allowed on the ACT's at least (even though a lot of people don't take it). I wouldn't be surprised if some college professors don't let you use it either.</p>
<p>Hecatonchires, I'll defend my choice of words :)</p>
<p>You're exactly right. The TI-84+ is a replacement for the TI-83+. And, it's just that.</p>
<p>To be fair it does have more memory / speed, more applications pre-loaded, and USB connectivity.</p>
<p>But, considering that there is a $20 difference between the TI-83+ and the TI-84+, as well as a $30 difference between the TI-89 and the TI-84+, and taking note of the power differences between the calculators, it is a much wiser decision to purchase the TI-89.</p>
<p>Most bang for your buck.</p>
