Asus Zenbook Duo 2025 Vs Lenovo Yoga Book 9i Review. I've been racking my brain over the zenbook duo and the lenovo yoga book 9i and this is my analysis of the differences: This month i found out about the new (april 2024) lenovo yoga book and was fascinated with the dual screen, keyboard and the specs of the laptop.

Though similar, one has an edge over its peer. I would like to buy the lenovo yogabook 9i laptop (the one with dual screens) before the end of the year.
