Choosing between the Dell Inspiron 14 and the Lenovo ThinkBook 13x involves considering your priorities. If budget is a primary concern, the Dell Inspiron may be a good fit, typically offering solid performance for everyday tasks such as web browsing, document editing, and media consumption at a more affordable price. However, if you are looking for a device with higher build quality, better portability due to lighter weight and smaller size, and potentially superior performance for more demanding applications, the Lenovo ThinkBook 13x may justify the extra expense. Keep in mind, though, that investing in the ThinkBook 13x also often means benefiting from a sharper display and longer battery life, which can be crucial for those who need to work on the go without frequent recharging.

PCMag
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."
