HP HP49G Graphing Calculator

Overviews

Is it possible to have it all--brains, beauty, and brawn? Hewlett-Packard certainly thinks so, and its HP 49G graphing calculator is its shining example.

There's no getting around the cool styling of the 49G: complete with a sleek metallic blue exterior and a groovy translucent blue hard slide cover, the 49G commands attention. When we were using it in public, it received plenty of looks and inquiries.

But how does it measure up in terms of power? Competing with the notorious Texas Instruments TI89 advanced graphing calculator is tough business, but HP pulls it off with some success. This graphing calculator has all the bells and whistles, including a whopping 1.5 MB of user memory; 2 MB of flash ROM, which enables future software upgrades; a built-in Computer Algebra System (CAS); math, scientific, statistical, financial, and 2-D/3-D graphing capabilities; programming capabilities with reverse Polish notation, assembly, and HP Basic languages; and a unit-to-unit and PC/Macintosh connectivity feature. It also features an equation solver, vectors, lists, arrays, matrices, expressions, and object storing.

One key feature we liked is the history screen, which displays what you've already input, so you can reference it to determine what went wrong and correct it. Another notable function is the 49G's alarm function. You can set the date and time on the calculator, and program the alarm along with a text message to remind you of appointments. You can also set control alarms, which perform functions such as automatically running a program when you're not using the calculator. Additionally, the calculator emits beeps when you enter an incorrect function, which can be annoying at times--especially when you're already frustrated.

One of this calculator's flaws is that it is hard to read the second and third functions above each key. In keeping with the calculator's sense of aesthetics, the print is in blue and red, which is difficult to see, especially in low lighting situations. It also has a one-touch X-variable key, but no Y- or Z-variable keys.

We wished the manual had gone into greater depth and provided clearer examples, but this might be a concern only to those who don't immediately get the full functionality of the 49G. Unlike some manuals we've seen, the 49G does not show both the necessary keys needed to input an equation along with how they appear on the screen. We also would have liked for the manual to include more examples.

If style is just as important to you as functionality, the 49G is the coolest looking calculator we've seen. But if it's pure power you're looking for, you'll probably be just as pleased with any one of the 3-D graphing calculators currently on the market.

Pros:

• Sleek exterior
• Lots of memory
• Full functionality

Cons:

• Alpha and second functions somewhat hard to read
• Manual not fully fleshed out
