The Graffiti shorthand for Palm PDAs [1]. It still far outshines any handwriting recognition systems available on modern devices both in terms of speed and usability.
Also, not really an individual product, but I miss durable consumer devices - I used a flipphone that had survived being run over by a tractor for years after the fact, and my old laptop could probably stop a bullet. If we could develop touchscreen glass that didn't break on a strong sneeze, I would be delighted (though the phone repair industry, perhaps less-so).
