Totally cool!

Non disclosure.... I love HP calculators and RPN. I did my undergrade in EE with an HP-45... My grad school with an HP-15C. I now have an HP-35S and a 50g.

This app is awsome. Ive only gone through the basic tutorials on the ND0, and admit to being a newbie to the iPod touch, where I got it.... but this application is just freaking amazing!

Ill no doubt buy the ND1! Ive written, just for fun, some wxWindows emulators for the 15C. But this app rocks!

Highly recommended for anyone who understands that RPN is the easy way to go... lol!
