The Dell Inspiron 14 7420 and Lenovo IdeaPad 1 15" are similarly priced and both cater to general use with adequate performance for everyday tasks. The Dell has a slightly smaller screen with a taller aspect ratio and higher resolution, which can be better for browsing and productivity tasks. It also has more RAM, which can enhance multitasking capabilities. On the other hand, the Lenovo has a larger screen with a traditional aspect ratio, making it good for multimedia consumption, and its battery life exceeds that of the Dell, which may be vital if you often work on the go. Both models offer touchscreens, backlit keyboards, and are light enough for portability. If you prioritize a higher resolution and better multitasking, you might lean towards the Dell, but if longer battery life and a larger screen size are more critical for your use, the Lenovo could be more suitable.

The Lenovo IdeaPad 1 15" has a better screen than the Dell Inspiron 14 7420 for general use.
For general use, both the Dell Inspiron 14 7420 and the Lenovo IdeaPad 1 15" offer screens with adequate resolution and brightness, but they may not have the superior panel types found in higher-end models which provide better color reproduction and viewing angles. When considering engineering and design, these laptops' displays fall short in covering the wider color gamuts such as DCI-P3 and Adobe RGB, which are critical for precise color work and detailed design. For 3D and gaming, the lack of high refresh rates limits the ability to render smooth motion, and although the resolution might be acceptable, the panel types do not offer the fast response times preferred for these activities.

"Notable qualities of the Inspiron 7420 2-in-1 include the 16:10 aspect ratio, strong hinges, 12th gen Intel CPU with optional GeForce MX graphics, and easy serviceability. Such features would typically cost hundreds of dollars more on higher-end alternatives from competing manufacturers. The value proposition is therefore relatively high for users looking to maximize bang for the buck."

"The Lenovo IdeaPad 1 15" is affordable and pretty efficient. At the end of the day, the Lenovo IdeaPad 1 (15″, 2023) is one of the better affordable laptops money can buy right now. It has a decent performance, albeit coming from a CPU that is based on old architecture. Playing low-intensity games is possible but at low to medium settings. We are really happy with the cooling setup, but the main event here is the battery life. We got 9 hours of either Web browsing or video playback, which is a great result. Especially if you compare this device with the ASUS E410."
