Apple to Begin Selling Revised Newton: Cupertino, Calif.-based Apple Computer Inc. will sell new versions of its Newton hand-held computer next month based on revised operating software that can recognize handwriting better. The company said the new units, dubbed Messagepad 120, would sell for $699. Software upgrade kits for current owners of Newtons will cost $109. But the original Newton, models 100 and 110 that went on sale in 1993, are not powerful enough for the new software. Owners of those models will receive a $100 rebate if they buy a new one. The pen-based computer has been criticized for sloppy recognition of handwriting. The new version’s base programs make it easier to share data with a desk-bound PC.
