The webOS platform is not quite dead yet, and is pretty capable if placed in the right hands. We’re talking about the HP 12c financial calculator being emulated on webOS, thanks to the magic of Javascript emulation. While this is not the full application, it will still let you perform all the relevant calculations that you’ve ever wanted to do with this classic. The program is known as Calc12c, where it will support both the Pre and the Pixi, delivering haptic feedback for each press of the on-screen button. This is definitely the more economical way of going around things since a physical 12c will cost you around $70.
