Really cool calculator, the touchscreen is a nice touch.

Great calculator! Does everything and more. The online program is great.

Hp has surpassed my expectations. It is compact, light weight and easy to use, One thing which makes it stand out its competitors is the battery timings. Since its purchase, I had to charge it for only one time which was recommended after opening. I could not find the exact battery timing. I have used it for my Mid Term exams preparation for the last ten days. In my point of view, other competitors must learn from Hp in ergonomics, light weight, battery timings and compactness, Hp has done an extremely wonderful job. I would recommend the product to every graduate student and researcher.

The HP Prime is probably geared towards more advanced mathematics while the TI calc. seem to be made more for the high school and early college students. I would say I definitely prefer the HP Prime in terms of speed of processing commands, the ability to adjust the graphing window quickly with the touchscreen, and the library of built-in functions is much more robust. Although this HP it's a little bit cheaper than the latest TI, it's clear that they decided to put more focus and money into the hardware of this amazing calculator.

Ease of use Impressive lightweight compact durable
