Who should choose Lenovo Yoga 9i Gen 9
Lenovo Yoga 9i Gen 9 is the stronger fit when its leading dimensions match your primary use. Configuration checks: CPU and GPU, memory, storage, display, ports, weight, and battery capacity. Then ask whether the product removes a concrete problem with the device you already own. If the gap is small and there is no real pain point, waiting for a price drop or a change in workload can be more rational than upgrading for novelty alone.
Who should choose ASUS Zenbook Duo (2024)
ASUS Zenbook Duo (2024) is the better fit when more of its strengths overlap your priorities and its weaker dimensions remain acceptable. Switching costs: operating system and app licenses, docks, chargers, peripherals, data migration, and repair policy. A higher total can still deliver lower practical value when that burden is large, so compare the score lead and switching cost on the same baseline.

Scope and limits of this comparison
This comparison is a structured decision aid built from published specifications and stored representative configurations. Scope and limits: application optimization, sustained-load heat and noise, battery wear, and panel variance. The scores are relative indicators for setting priorities within one category, not an absolute quality ranking. When a new configuration or verified specification becomes available, the catalog and its comparison pages are regenerated together.
