The ASUS ZenBook Pro Duo 15 is significantly more expensive and offers top-end performance with a high-resolution OLED screen, making it suitable for intensive tasks like 3D rendering, machine learning, and engineering work. Its extra screen and powerful graphics also make it suited for gaming. However, it's heavier, which affects its portability. The Lenovo IdeaPad Slim 7i is considerably less expensive and lighter, lending itself to better portability and longer battery life, making it a good choice for general use and everyday tasks. If graphics and high-performance computing are less critical to you, the Lenovo may be a more cost-effective choice. Give Feedback

The ASUS ZenBook Pro Duo 15 is very good for general use, while the Lenovo IdeaPad Slim 7i is good.
The ASUS ZenBook Pro Duo 15 stands out for general use with its high-performance CPU, substantial RAM, and OLED screen that delivers excellent color coverage and brightness, but it's less portable and has shorter battery life compared to the Lenovo IdeaPad Slim 7i, which offers decent performance for everyday tasks, a good IPS screen, and longer battery life in a lighter and more compact frame. While the ZenBook Pro Duo's keyboard and speaker qualities are notable and the dual screen could enhance productivity, its tradeoff includes higher operating noise and less effective heat management, whereas the IdeaPad Slim 7i offers a quieter and cooler experience with a very good keyboard and speakers but lower storage capacity and less powerful graphics.

"Benchmarks aside, the Asus ZenBook Pro Duo is hard to compare with other PCs. Its closest competition may be a multi-monitor desktop, or a laptop with an attached travel monitor. The Pro Duo is more portable and versatile than either of those options, especially with the software tools Asus has thrown on top. For a certain niche of artists, media creators, and gamers, all that might add up to something special, even if it’s unattainable for the rest of us."

"Among Lenovo's multiple laptop brands, the IdeaPad family is decidedly the one designed for consumers: people who want decent performance at a reasonable price. Consider, then, this laptop a paragon for the pickier members of that crowd. With a 14-inch touch-enabled display, a comfortable keyboard, an Evo-certified Intel Core i7 11th Generation CPU, and the latest Windows 11 operating system, the IdeaPad Slim 7i Pro ultraportable ($1,199 as tested) is a slick mainstream machine at a bit of a premium price, and quite capable for everyday tasks."
