I wrote a post about my initial experience writing with USI pens: https://www.jpwhiteside.com/the-promise-of-usi/

I also contrasted my experience with USI against my favorite, Wacom EMR: https://www.jpwhiteside.com/usi-v-emr-pen-experiences/

But what is the experience like with other pen technologies? Which perform the best? In this video, I show what it’s like writing with the dominant digital ink technologies available on devices sold in the United States in 2025.

Take a look!
