Willy's RPN-67 and 97 have fulfilled my wish list 29C, 34C, and even 15C wishes.

Even though I have the real things, Willy's calcs let my mind get creative with mathematical and adventutres with the added thrill of vintage RPN programming.

Who needs Disneyland, Magic Mounain, or even Disney World?! Cuvee calculators are the real amusement parks!

I think Matt got this exactly right. Like many users, I love using both the originals and the simulators. With the latter, we can have the HP-67 of our dreams, and if you can imagine a new enhancement, Willy has probably already added it. It is really worth having both iPad and iPhone so you can get the maximum benefits of these fine simulators. RPN-67/97 are really the flagships. Five years ago I was looking for RPN apps and stumbled on Willy's RPN-45 which was then his flagship, really a turbocharged HP-45. Now he's taken these possibilities to a whole new level.

Personally, I think it's worth it to buy all of his simulators, because it gives you the different feel of the originals.

Hopefully a new generation will be able to learn about the originals through these simulators.
