Now that's a very interesting idea. I could re-purpose my old iPhone that sits unused in a drawer, along with my old iPod touch etc.

Then again nobody seems to make hp-like keyboards even for regular circuit boards etc. Even the DM-42 couldn't make a decent keyboard for their hardware calculator. So creating a proper snap on keyboard of sufficient quality seems unlikely, unless some company focuses on reproducing the hp-like keyboard. Having a snap on iPhone market might motivate them.
