The strengths of the hPDA concept — ruggedness, reliability, and simplicity — derive from its preferred medium, the humble 3×5 card. But as hard as it is for me to admit, paper does have its limitations. Ink affixes the data to the storage medium statically, and in doing so it limits the user’s ability to manipulate the data.
On the other hand, while electronic storage offers magnificent interactivity, the data manipulation and search experience can be more complex and intensive than on an index card. If only index cards could sort themselves!
But until scientists figure out a way to manufacture smart 3×5 cards (and for any scientists reading this, there’s probably a Nobel Prize in it for you), here’s the best of both worlds — a quick hack for my wife’s Palm that blends the yin of a PDA with the yang of a hipster (or is it the other way around?). It uses three small Rollabind rings affixed to a sheet trimmed from a poly file folder, which is then slipped into the leather holder’s card pocket. A stylus with a built-in pen allows her to translate between the two with ease. The hPDA is perfect for shopping lists, quick reminders, and taking notes on the fly. The PDA manages her complex and ever-changing calendar.
Now if I could only get her to use my hPDA templates…
