Okay, so I've had the same graphical calculator for about the last 5 or 6 years and it's served me very well (it's an old bulky Casio), but I figure it's time to invest in a new one to serve me for the next 5 or 6 years.

What graphical calculators do you guys have and what are the good and bad features of them?

My calculator does numerical integration, but I'm curious if any calculators now can do analytic integration. Ideally, it'd be pretty awesome to have a PDA with Maple or MATLAB on it, but a calculator with some basic mathematical tools would do me just as well.

Any suggestions?

Texas Instruments makes pretty good ones.

EDIT: Yeah, it has lasted me about 4 years or so, still works great. Bringing it to college with me.

I've still got my TI-86, and while it took some water damage so a couple rows of the LCD don't work, it's otherwise lasted me 6 years or so.

I had a TI-83+ until it was stolen from the glove box in my car. Now I just use Google.

I used a Texas Instruments TI-83 for 6+ years and still do. It's reliable when doing graphs and such. The problem is the limited screen size, it can only put out so much info. While I'm not going to recommend the TI-83 because it must be considered outdated as graphic calculators of today, I heard good things of newer Texas Instrument products.

I've had the same Ti-89 since they were first released in 1998, and its served me very well.

Of course, at the end of the day, and Graphing calculator is a graphic calculator, so looking at features is kinda silly. I'd look for usability and durability first. Also, depending on what kind of work you'll be doing in the future, there is no shame in just using a laptop with Mathematica, Maple (shudders), or Matlab.

Doesn't the TI-89 do analytical integration? It's not as powerful as Mathematica's engine but it should do most things.

If you're serious about it you're best off getting something like an Asus Eee PC (get the 901 or other model with the Atom CPU) and putting Mathematica on it.

The TI-89 is amazing. Also, for homework and perhaps looking at which you might want to buy, have a look at an emulator called VirtualTI (it's free). You can pirate the ROMs for all of the TI's from 82 to 92, or pm me.

I had a TI-83 Silver Edition that recently just stopped working, but what I use now is an old HP-48g. Reverse Polish Notation FTW! Any new one I get will be an HP.

You can't beat the good old TI-83+

Yea, it does. The TI-89 Titanium is a great device.

A loyal user of the TI-83+ Silver Edition. Have some fancy apps on it loaded so it can do some things that the TI-89 can do

I had a Ti-83+ and a TI-89 Titanium.

A word of warning, a lot of classes won't let you use the TI-89.

why cause of note storage? i can do that with any ti-??

Because it can do analytical derivation and integration. It give you the answers to most problems in an entire calculus sequence.

I struggled with Texas kit, I prefer Casio.

I have had a TI-83+ for many years and frankly I absolutely beat the **** out of it and it hasn't complained a bit. I'm not sure what kind of device you need though, this may not do enough for you. I even had it stolen once and got it back a full year later after somebody Dremeled my name off it. These things are tanks and keep going and going and going.
