To make this decision, focus on your needs. The Dell Inspiron 14 7435 may offer solid performance for general use and can save you money if intensive tasks like gaming or engineering software are not priorities. The Lenovo Slim Pro 9i, on the other hand, typically costs more but may provide enhanced performance and features, which could be beneficial for demanding applications such as 3D rendering, machine learning, or gaming. Consider the Lenovo if you need top-tier performance and are willing to invest more. Bearing in mind battery life and portability, the Lenovo might offer longer usage times and might be slimmer and lighter, which can be crucial if you travel often or work on the go. Make sure to weigh these aspects against the price difference and your budget. Give Feedback

Eric Grevstad | August 2023
"We see no shame in an economy laptop missing the four-star mark. Frankly, we considered giving the Inspiron 14 2-in-1 three-and-a-half stars for its low price, competitive performance, and long battery life. Unfortunately, working with a screen that can't deliver at least 300 nits of brightness is simply no fun to the point of detrimental. Still, if you're looking for a convertible laptop on a tight budget, it's worth keeping an eye on Dell's sales and discounts. That Lavender Blue model is fairly tempting."

"The Lenovo Slim Pro 9i is an impressive laptop with a brilliant Mini-LED display, a powerful 100-watt version of Nvidia RTX 4050 graphics, and excellent connectivity. Having run the Cinebench benchmark again, we were impressed with the CPU performance. That makes the Slim Pro 9i is an easy recommendation, especially for those who care about GPU and CPU performance. It’s also a fantastic choice if you frequently view HDR movies and games on your laptop."
