The ASUS ZenBook Pro Duo 15, being more expensive, offers higher performance, especially for tasks such as 3D rendering, machine learning, or gaming, due to its robust hardware. Additionally, it typically comes with unique features like a secondary touchscreen, which can enhance productivity. The Dell Latitude 14 7490, on the other hand, while less powerful, is likely more portable, offers longer battery life, and is more cost-effective. It is a solid choice for general business or personal use where portability and battery life are significant considerations. Consider the Dell if you prioritize mobility and value for money, and the ASUS if top-tier performance and innovative features justify the higher cost for you. Give Feedback

"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."

"The Dell Latitude 7490's got the speed you need (and then some), a keyboard that's comfortable enough for writing all day long and a battery that supports a full 8-hour workday. If only the display were brighter and it managed heat better. If you need every minute of battery life you can get, the extended-battery version of the Lenovo ThinkPad T480 lasts 8 hours longer than the Latitude 7490, but its display is much less colorful."
