Is the Lenovo worth $225 more than the Dell?

Yes if you keep many apps open or edit photos, because 16GB of RAM and the 120Hz screen make daily use noticeably smoother. If you mostly browse and stream, the Dell at $499.99 covers that fine.

Which is better for students?

The Lenovo, mainly for the 16GB of RAM, which handles research tabs, video calls and documents at once. The Dell works for basic coursework but will slow down sooner with 8GB.

Which has the better screen?

Both are 15.3-inch 1920 x 1200 touchscreens. The Lenovo adds a 120Hz refresh rate and 400 nits of brightness, so scrolling and outdoor use are better; the Dell is 60Hz.

Can I upgrade the Dell's memory later?

It ships with a single 8GB DDR5 module at 5600MT/s, so a swap is possible but not something to count on for a cheap laptop. The Lenovo already has 16GB, so no upgrade is needed.

The Dell at 3.3 lb versus 3.5 lb for the Lenovo. The difference is small and most people won't notice it in a bag.

The Lenovo should stay useful longer because of its 16GB of RAM and stronger Core 7 processor. The Dell's 8GB is the first thing to feel dated.
