Saunders DeskMate II Plastic Storage Clipboard with Calculator, Letter Size 8.5 inch x 12 inch, Orange (00543) Review

Average Reviews:

(More customer reviews)I have been through clipboards for myself and my personal trainers and I think that if you want a storage clipboard, then get a metal one.This is hard to open because the plstic is too soft and it just bends when you try to open it and no way you can fit any pens inside!The calculator's buttons keep falling out.

Casio FX-115ES Advanced Scientific Calculator with 2-Line Natural Textbook Display Review

Average Reviews:

(More customer reviews)I bought this calculator's distant ancestor six or seven years ago in College and loved it ever since.The old model was the first calc that gave you graphing calculator editing capabilities in a small calc package and it was a steal for the $12 or $14 I paid for it then.This new generation is nothing short of a quantum leap forward.For the first time you can enter equations exactly as you would write them.The font switches to a smaller size, so you can review the whole equation at once.It also has a solver funtion that is intuitive and quick; I used it all the time on open channel flow problems, or any equation that would require more than mild rearranging of terms.This may be the only calc on the PE approved list that has this ability.

Other high points:
* excellent battery life and solar ability
* Table function

Minor quibbles:
*you may have to slow down the pace when keying in as it will miss keystrokes if you type too fast
* you have to hit Shift to get to 'X' (alpha) or Pi
* when editing an equation, very slow to cursor to where you want

Texas Instruments BA Real Estate Financial Calculator Review

Average Reviews:

(More customer reviews)During the many years going to college (I majored in Finance), working as a Banker, and now as a Realtor/Loan Officer, I have used many different financial calculators made by Sharp, HP, and Texas Instruments, etc. Each of the calculators I've tried has some good points and some bad ones. However, if you work in real estate, this calculator is made for you. It is loaded with excellent features specifically designed for this industry. I paid over $80 for my calculator when it first came out, and I felt I got every penny's worth. At the current price of less than forty bucks, it's absolutely a bargain!
Another reviewer on this page complains about the responsiveness of the keys. I simply don't have any problem like that at all. He or she must have had a defective one. I always tap the keys very fast, and the numbers come out all right.
In short, if you're heavily involved with real estate and mortgages, I highly recommend you to give this calculator a try!

Texas Instruments TI-86 ViewScreen Calculator Review

(More customer reviews)IMO, this is one of the best calculators ever made. My original one ended up with some problem on the display and I was pleased to find I could still get a used one. I'm an engineer and this calculator fills the opening between the simple stock computer calculators and the more advanced computer programs (i.e. matlab, mathematica...).

TI-Nspire CAS Graphing Calculator Review

Average Reviews:

(More customer reviews)This is a calculator with tons of potential, however it is not nearly as user friendly as every other TI graphing calculator is.I'm an AP Calculus teacher and ordered one of these through school funds to test out.It can do everything that the TI-89 does and has much more potential than the TI-89, but the thought of teaching my students to use one of these just scares the bejesus out of me.

Pros:
1. Large screen with good resolution.
2. little green letter buttons make it easier to enter commands.
3. WYSIWYG typing means you don't have to remember calculator syntax.It's much easier to enter a definite integral or limit.
4. Graphing window allows you to graph rectangular, polar, and parametric equations simultaneously.
5. Click and drag feature on the graph screen is nice.

Cons:
1. The letter buttons are always in the way while I'm trying to enter numbers.
2. Screen can be difficult to read.
3. There is not a model that hooks up to a TI presenter.It does come with software where you can use a computer version of the calculator (assuming you have an LCD projector), but it's much slower than simply hitting actual buttons.
4. Finding max, min, roots, and intersections takes longer than on the TI-89.
5. When you do find the things from my #4 con, the calculator displays them right in the middle of the graphing screen, so you have to click and drag them out of the way to continue viewing the graph.
6. The "y=" screen is included as part of the graph screen, taking up graphing space.
7. Viewing a function table isn't difficult, but I can't figure out how to view a window containing ONLY the function table.It splits the screen with the graph on the left and the table on the right.This keeps you from being able to see several function values at the same time.Also I can't figure out how to close the table. I'm sure there's an easy way, but due to the completely inadequate user manual I have no idea what it is.
EDIT: I figured out how to view a function table on a different page/tab in the calculator, so the split screen problem is solved and it's much easier to close the function table.It still is not very intuitive at all and if I weren't very tech savvy I'd have never figured it out.
8. I have yet to find a differential equation graphing mode, and internet searches lead me to believe there isn't one.Why in the world would TI include this with the TI-89 and not with their new, supposed top-of-the-line model?

I may edit this as I find more pros or cons.I've had this calculator for 3 or 4 months and I do get it out on occasion to give it another shot, but each time I'm just as disappointed as the last.I keep think it just has a steep learning curve and I'll eventually catch on but it's not happening.That being the case, I have a feeling that if I tried to get my students to use this calculator I would be spending too much time just teaching them to use it.

If this calculator was only $50 and the TI-89 Titanium stayed at about $150 I'd still encourage my students to get the 89.

Texas Instruments TI-NSpire Math and Science Handheld Graphing Calculator Review

Average Reviews:

(More customer reviews)Strengths:

The document management system -- multiple "problems" can be kept in the calculator at the same time, and each problem keeps its own variable names; good graphing capabilities; ability to split the screen and work with multiple views of the same problem; spreadsheet application.The calculator has 5 "applications" (calculator, graphs & geometry, spreadsheet, data & statistics, notes), and information can be shared between them.

Weaknesses:
The documentation is very poor.There are two user guides, with considerable overlap in the contents.In User Guide Part 1, which comes packaged with the calculator, there are 25 pages on the Graphs & Geometry application, and the information on how to actually plot a graph is barely mentioned.User Guide Part 2 comes as a PDF file, and has more detail, but is badly organized and missing a lot of information.For example, instructions for a number of operations say to "drag" something, but nowhere in the manual does it say how to do that.

Keypad: other reviewers have commented on the difficulty pressing the right buttons on the keypad.Even worse is the "mouse" operation.I finally discovered that dragging involves holding the center "Click button" while pressing the arrow keys on the "NavPad".It is very difficult to control the cursor with the NavPad, and doubly so when trying to hold down the click button.Also, what operation is done by a click or drag is dependent on where on the screen the cursor is, and it's difficult to control the cursor location with the level of precision needed.

TI-84 compatibility: This seemed like a great idea.However, as far as I can determine, there's no way to integrate TI-84 functions with TI-Nspire functions.When you put in the TI-84 keypad, you get a TI-84.With the TI-Nspire keypad, you get a TI-Nspire.If you want to transfer information from one to the other, it seems to be impossible.The only relevant information in the documentation about TI-84 mode is a warning that if you update the operating system, all your added TI-84 applications will be deleted.

Lack of software: The TI-84 has a lot of user-contributed software.There's almost nothing on the TI web site for the TI-Nspire.I also didn't find much with a web search, and some of what is available requires the CAS version.For example, there don't appear to be any built-in physical constants or conversion factors for units.I could switch to TI-84 mode and get them, but then what's the point of buying the TI-Nspire?

Summary:

This calculator does not appear to be well-engineered or well-supported by TI.I would recommend waiting to see whether they give it the support that it deserves.

Texas Instruments TI-89 Titanium Graphing Calculator Review

Average Reviews:

(More customer reviews)Before I bought a TI-89 Titanium, I had used a TI-83 Plus for four years. After taking calculus and learning about limits, derivatives, integrals, infinite series, Taylor series, differential equations, and multivariable functions, I decided that I would look for a calculator which was capable of symbolic computation. After analyzing my options, I decided on a TI-89 Titanium. The TI-89 Titanium is able to expand polynomials, factor polynomials, and do all of the calculus techniques that I mentioned -- symbolically and numerically. One of the other things I found helpful was the TI-89 Titanium's ability to plot direction fields using different algorithms (including Euler's method). One of the nicer things about this model (compared to the TI-89) is that it has USB connectivity (cord included) for installing applications and transferring data. Another nice thing is that it also supports connectivity to older model TI-89s via the old I/O port which is right next to the USB connector. I also found the "exact mode" very useful (exact mode will give you exact answers rather than decimal approximations). Yet, the most useful feature of this calculator is probably the "pretty print" feature which displays expressions as you would normally write them on paper. This feature allows you to easily see the expression that you typed in. All these features plus copy and paste ability make this calculator nearly perfect. My only complaint is that the cover does not initially slide on and off easily. However, I'm sure that with more use it will wear in. Overall this is a great calculator -- I recommend it

Product Description:
This advanced graphing calculator is packed with more features than you might know how to use. The TI-89 Titanium lets you perform the expected functions of an advanced model--basic math, algebra, calculus, graphs, matrices, and statistical functions--and do cool stuff like creating animations, graphing 3-D rotations, and plotting contours. Graphing functions include basic function graphing, parametric graphing, polar graphing, sequence graphing, 3-D graphing, and differential-equation graphing. Additionally, the TI-89 Titanium includes symbolic manipulation, constants and measurement units, statistics and data plots, a numeric solver, a text editor, programming capabilities, tables, a split-screen function, variable management, and the ability to link to other calculators or a computer.
The TI-89 Titanium's flash technology allows you to upgrade to future software versions without having to continually invest in new calculators. The 188 KB of RAM, combined with an impressive 2.7 MB of flash memory (three times the memory of the TI-89), are more than sufficient for your stored functions, programs, and data, and add welcome speed to go with the TI's reliability. You can create custom menus or use the default menu. Another cool feature is the Program Editor, which gives you the ability to write custom applications.

The large LCD is adjustable to your environment and can be viewed clearly under a variety of lighting conditions. The calculator also comes with an input/output port and cable, letting you synch up with other TI-89s or TI-92s, as well as a USB port and cable. An attached, hard slide cover protects the calculator from getting knocked around in your backpack. The manual that ships with the TI-89 Titanium is a killer, presenting over 500 pages of clear, concise definitions, function explanations, examples, drawings, and appendices. It's divided into well-organized chapters that cover all the major features of the calculator.
