The first and best of the PDAs, the Newton lasted only about 5 years and 8 models, but it made a lasting impact. Though the device got off to an inauspicious start, because of weak handwriting recognition, the quality and accuracy improved a great deal by the time Newton OS 2.0 was released in 1997.
If the Newton had sold well enough to survive past 1998, it would have ended up going to color like its rival Palm did. Apple would have also likely entered the smartphone market long before 2007. Even better, Apple’s phones and tablets would be built to support pen input, something Steve Jobs opposed but is becoming quite popular with devices like the Samsung Galaxy Note II and LG Intuition.
