Aha Software, founded in 1991, developed the patent-pending SmartInk technology that lets users manipulate handwritten text entered into a handheld computer the same way that they do typewritten text, for example, cutting and pasting text. The technology is intended to eliminate the need for handwriting recognition software, which is widely available but still the subject of consistent user complaints about unrelability.

Microsoft officials say the company will implement Aha's software into future technologies but did not specify any product plans.
