That's the one I have, right? Mine came in one of those clear plastic packages--no case, for $12 at Walmart. I wish I had a case for mine. This thing looks like it can do a lot, but all I do is punch in the distance, sin, and the angle--takes about 3 1/2 seconds.
I read recently that some of the cell phones now have 800 times the computer capacity that was used to send a man to the moon in 1969. I bet this little calculator has 8,000 times as much. Having this "computer" to do the one simple calculation I'll be using it for seems like a waste. Maybe I should learn to do more with it?
