From that video review, it turns out there is a way to have handwriting converted to text where you would normally need to use virtual keyboard (adding a note). Not clear if that's on device or requires internet connection. Or which languages are supported.

However that addresses some of my reluctance to create sticky notes, as they don't interoperate across Kindle platform. Yet handwriting is a lot quicker than using the virtual keyboard. With this I can create text notes more quickly and they'll be portable to all of the apps and other Kindles.
