 Awesome!!! October 24, 2009

Do you need to get an A on a calculus class? Do you want to get a 5 on a mathematics AP test? The TI 89 can solve the world!!
 The one for Electrical Engineers October 19, 2009

This is a second for me. I purchased my first as a returning student and it helped immeasurably with attaining my BSEE. Now I needed a second (and updated version) for work. Whether you are a student or working EE, this is the one to have.
ELECTRICAL ENGINEERING TOOL October 13, 2009
ALBERTO VARGAS (COSTA RICA, CENTRAL AMERICA)
As an Electrical Engineer, I know that usually a good calculator that is bought at University years, will most probably be with you for life. Mine is an old Casio FX-850P, which back then was a marvel!
Nowadays, my nephew is also studying Electrical Engineering, he wanted/needed a calculator.
A sort of netbook could have been usefull, since they are very small, light, portable, and it's possible to run all kinds of software. But some courses only allow calculators, netbooks and laptops are prohibited. In addition, a calculator is smaller (fits in your pocket), lighter, and the battery life is much much larger. (Have you ever run out of batteries in the middle of important work while using a laptop? It usually happens! Now imagine that in the mid of a test!!!).
After doing some research myself, looks like the TI-89 is the best tool currently available. (HP used to make the best ones, but on the past years most people seem to agree that quality is subpar, and usability has decreased. A shame).
Also important, most of my nephew's classmates also use TI-89's, so I bought this as a gift to him.
TI-89's are extremely versatile programmable calculators/computers. There is a very large community of users who have written software for those things not already within. And if required, anyone with some programming and technical knowledge can write their own programs.
My nephew has used it for a few weeks and so far is very happy. It has already been very useful with some of his classes.
