Most Thinkpads have terrible screens. Many used Thinkpads will need shims or otherwise under keyboards to stop them rattling. They also suffer from a number of issues such as electrical noise (i.e. coil whine), If you're thinking about a Thinkpad to replace a Macbook Pro, consider: - X220, X230 with IPS displays. Most aren't. Check for backlight bleed. - X250 with IPS display, but be mindful that the CPU is actually no faster than the X230 (15W U series vs 28-35W). X240 has weird buttons that don't work, avoid. - X1 Carbon, 1st or 3rd gen. Avoid 2nd gen as split backspace key will drive you insane if you ever use more than one keyboard. Again, be mindful of U series CPUs. - T5xx have better displays than T4xx in general. But if you don't want the extra size, then avoid AU Optronics displays on T420 and T430 series, as they are grainy and poor. I believe the Tx50 series has IPS display options, maybe on the s model?
