Thinkpad T420

Across 141 HackerNews comments, the T420 is repeatedly described as virtually indestructible. Users report dropping it onto concrete ("the concrete broke"), using it for 9+ years as a daily driver, dremeling it, and even briefly setting it on fire without failure. The 7-row keyboard is consistently hailed as the best ever shipped—"last-of-a-generation"—and the trackpoint (red nub) is beloved by Linux developers. Upgradability is a major theme: users swap RAM to 16GB, add SSDs, replace batteries, and even flash coreboot for full firmware control. Performance-wise, users are realistic: the T420 handles web browsing, coding (Python, Django, Elixir, Java), and 1080p YouTube fine, but struggles with 4K H.265/VP9 video playback and is unsuitable for gaming or video editing. The single biggest complaint is the screen: nearly all units shipped with mediocre TN panels (poor contrast, bad viewing angles, 6-bit color), and finding a good IPS replacement is described as expensive and rare. Battery life on original packs is universally described as poor ("five minutes," "both batteries are shot"). Some users have moved on to T440p or T480 models for better screens and modern CPUs, but express nostalgia. Sentiment is overwhelmingly positive for the laptop's intended use case as a rugged, repairable, Linux-friendly productivity machine.
