HP is throwing up awesome-looking applications that replicate the functionality of calculators from the past. iPhone Central:

Hewlett-Packard (HP) today announced iPhone-app versions of three classic HP calculators: the HP 12c, HP 12c Platinum, and HP 15C.

This is a crazy idea, but at least one commenter on the original article claims that he would buy an iPhone just to have an app of the 11c. The screenshot of the app makes it look well-designed and nostalgia-tinged.
