At Office Evolution, a blog hosted by ZDNet, Marc Orchant points us toward Microsoft MVP Terri Stratton's summary of new Tablet PC features in Vista.

The biggest value for me will be this:

Train Your Tablet PC to Recognize Your Handwriting

There are two ways to train the handwriting recognition in Windows Vista. While Handwriting recognition personalization is enabled by default, it will have no effect until you either submit samples using the Handwriting Recognition Personalization Tool or opt into Automatic Learning.

The Tablet team often hears rumors that the current Tablet PC API "learns" your handwriting; but since they never wrote code for that, they just laugh. The Tablet PC today doesn't learn the way you write; rather, you learn to write the way it can understand. And it's good, but it could be better. In Vista, it will be.

As a Tablet PC programmer, I'm more interested in API changes. But this list of UI changes will affect a lot more people.
