Choosing between the Dell Latitude 14 7490 and the Lenovo Flex 5 16 involves considering a few key differences. The Dell is often significantly less expensive, which could be appealing if you are on a tight budget. It is also lighter and has a smaller screen, which may be better for traveling or for those who prefer a more compact device. On the other hand, the Lenovo Flex 5 16 has a higher resolution screen, which means crisper and more detailed images, especially useful for creative tasks or multimedia consumption. Additionally, the Lenovo is a 2-in-1 convertible, so it can function as both a laptop and a tablet, offering versatility for users who want the extra functionality. The Lenovo also comes with the newer Windows 11 Home, whereas the Dell is pre-installed with Windows 10 Pro, which might be preferable for business users who require specific Pro features. Keep in mind that the increased capabilities and recent features of the Lenovo come with a higher price tag compared to the more budget-friendly Dell. Give Feedback

How the Dell Latitude 14 7490 and the Lenovo Flex 5 16 compare to other laptops
"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."
"The Lenovo IdeaPad Flex 5 is a solidly equipped, 2-in-1 in the lower price segment. Performance is definitely sufficient for everyday tasks and in tests the battery proved itself to be very economical. That aside, there is a lot of standard fare on show and a search for real highlights ends in vain. The low color coverage and reflective display can be avoided by going for an optional 2.5K display but this also presumably results in poorer battery life. The cooling uses only one fan and leads to a raised temperature on one side of the device under load. Additionally, there is very loud fan noise, also under load or when gaming. On top of that, we also occasionally noticed electronic noises."
