Interesting comparison—what stoodBlog comment creation out to me is how the Ideapad Slim 3 manages to stay so thin at 7.9mm while still packing in a decent battery life of around 11–12 hours. On the other hand, the ThinkBook 14’s all-metal build and 2-in-1 flexibility clearly position it for a different kind of user who values durability and versatility. It would be great to see a side-by-side on real-world performance, since specs only tell part of the story.
