Hi every body

Yesterday, I bought a new financial calculator TI BA II

plus for taking CFA exam. Before, I also owned an HP 12C.

After doing some TVM (time value of money) exercises, I

realized that TI BA II plus was faster than HP 12C very

very much when solve for i (interest) and IRR. so, I

wonder why most of professional financial analyst like HP

12C than TI BA II plus ?

any comments?

thanks
