Even though the software, due to appear in devices Nov. 7, can match against the many different types of handwriting in its database, it can't adapt to an individual user's style of writing and learn, for example, that the person never crosses his or her T's.
That's been a source of some debate within the company. Chief Software Architect Bill Gates is pushing to let the operating system begin to recognize an individual's handwriting quirks and expand the database on that user's machine. But others within Microsoft say such a capability could do more harm than good, and the company would do better to just update the operating system's master database periodically.
