Newton Newton is an operating system introduced by Apple Computer, Inc. in 1993. Frames are the central data structure in Newton. All are small enough to hold in one hand and weigh around one US pound.
Battery life is about one day's worth of continuous use.
From the very lowest levels, Newton supports recognition. Its handwriting recognition was highly publicized when first introduced. The recognizer allows free-form input of printed and cursive writing. The recognizer uses contextual information to limit both types of characters within specific fields and combinations of characters within words. The latter relies heavily on a dictionary-only words appearing in the dictionary can be recognized.
