You can see the HP 30S features and overview on the HP website at:

They're selling it online for $15.99. Believe me, it's worth the price!
Unreal. I remember when HP's first calculators came out 30 + years ago. $$$$$$$
It didn't take long for the price to come down, with interesting results: in 1975 I walked into the student bookstore at the University of California at Berkeley, my alma mater. There was a BARREL with a sign over it: "Your Choice - $3.99." Inside was the store's entire supply of slide rules, some of which had sold seven years later for over $150.00.
