<p>The TI-84 is good enough for me. I don’t think I’ll ever need a better calculator.</p>
<p>you probably never will, TI 84 is good enough for all of high school and most of college mathematics as far as I know…</p>
<p>I have the TI-89 Titanium. </p>
<p>It is the biggest piece of crap I have ever owned. I hate it. I hate it. I hate it. I am seriously considering sueing Texas Instruments over it.</p>
<p>I have the Ti-30 I bought it new in 79… because it was cheaper than my K&E slide rule…
I also keep buying them at flea markets if they are the solar model… I have three now
I also have the Ti-83+ emulator for my computer and I find myself using that more and more no batteries needed download upload instantly etc…</p>
<p>But
I just bought a Nspire which also has ti-84+ keyboard and is fully usable for all TESTS (my wife and I went back to college) and need of all things Algebra…
and I have to say I am impressed with the ease of use and upgradeability.
I snagged mine off ebay for $85 and there are several at the same price all the time…
Have a great day ALL!
