Which is better for everyday school and office work?

The Dell DC15250. Its Core 3 100U, 512GB SSD and 120Hz screen handle documents, browsing and video calls with more headroom, and it costs less right now.

Which laptop lasts longer on a charge?

Neither figure is directly comparable: Dell rates 8 hours, while Lenovo lists only a 47 Wh battery. Expect similar all-day-light use from both, and check real-world tests before relying on either number.

Is the Lenovo worth the extra $24?

Only if weight and a number pad matter most. Otherwise the Dell gives you double the storage, a fingerprint reader and a faster screen for less.

Can I upgrade the storage later?

Both use SSDs, but the Dell already ships with 512GB, so you are less likely to need a swap. The Lenovo's 256GB is the tighter limit from day one.

Which is better for travel?

The Lenovo at about 3.4 lb versus 4.2 lb for the Dell. The difference is noticeable in a backpack, but the Dell's brighter feature set may matter more day to day.

Do either have a touchscreen?

The Dell listing states touchscreen support; the Lenovo listing does not. Confirm the exact model at checkout if touch matters to you.
