QUESTION
What is the best used laptop to buy?
Best used laptop for most people: a Lenovo ThinkPad T490s or a Dell Latitude 5420, depending on the deal you find.
- Pick the ThinkPad T490s if you want a proven business laptop that is durable, portable, and good for everyday work, school, browsing, writing, and video calls.
- Pick the Dell Latitude 5420 if you want a newer-feeling Windows business laptop and can find one with 16GB RAM and a 512GB SSD.
- Pick the Dell XPS 15 7590 only if you want a larger, nicer-screen laptop for creative work or media and you are comfortable checking battery condition, thermals, and wear more carefully.
Minimum specs I’d look for used in 2026: 16GB RAM, SSD storage, 1080p or better display, working webcam, healthy battery, and Windows 11 support if you need Windows. Avoid cheap listings with 8GB RAM unless the price is very low or the RAM is upgradeable.
