    The best and most eonomical choice for any science student

    I have been using this for the past year and it has worked perfectly.
    The form factor is just amazing. It is very thin and light as compared to the ones available a few years back. The solid cover is very useful as it prevents the calculator itself from getting damaged. It has everything that a science as well as engineering student will ever need (to do on a calculator ;))

    This does not have the notebook display, which however, i dont feel is very helpful. If you plan on using this calcula...

Speedy processor (I use 69! - 69 factorial - as a good calculation to check speed in any calculator).

    Con: Very few and probably very minor. Just wo...
