When I started studying engineering in college I purchased a TI 89 because of the fancy reviews I read here, Afther taking my first calculus exam I changed my mind and changed it for an HP 49, the HP 49 is definitely made for engineers. With the TI you only get answers for exams but wiht the HP you get all the steps and it is as easy to use as a TI.
