This is an AMAZING Calculator!

This RPN calculator is truly amazing! ... both in its current capabilities and in its potential for future development. For anyone whole truly appreciates a powerful fully programmable scientific calculator, I have this simple word of advice: GET IT NOW! You will not be able to put it down ... but also a word of warning: be careful, because once you discover what this calculator can do you may end up "wasting" a lot of time because it can be very addicting. Definitely 5 stars.
