IBM

IBM commands near-legendary status in the r/BuyItForLife community, built almost entirely on the reputation of its vintage hardware — particularly the Model M keyboard and classic ThinkPad laptops. The Model M is the single most-mentioned product and is treated as the defining example of a BIFL purchase, with units from the 1980s still in daily use. The brand-generic comments reinforce this picture while adding ThinkPad nostalgia, but both sources converge on a critical caveat: IBM's quality legacy belongs to the vintage era, and Lenovo-era ThinkPads are explicitly not considered the same lineage by the community.

The high-volume Model M analysis (98 mentions) and the even higher-volume brand-generic comments (270 mentions) agree strongly that vintage IBM hardware — especially the Model M — is among the most BIFL-worthy hardware ever made, warranting a strong recommendation on its own terms. The verdict stops short of 'Strong recommend' at the brand level because the community explicitly warns that IBM's legacy does not extend to Lenovo-era products, and practical friction (PS/2 adapters, noise, modern compatibility) means buyers must go in with clear expectations.

IBM's vintage hardware is celebrated for extraordinary longevity, repairability, and build quality that modern equivalents rarely match. The Model M keyboard in particular is cited as the gold standard of durable consumer electronics.

• Model M keyboards reported in daily use after 30–40 years with no failure
• Buckling spring mechanism widely considered the best typing feel ever made
• Steel backplate and all-metal construction make keyboards nearly indestructible
• Vintage ThinkPads praised for tank-like build, drainage channels, and easy repairability
• Unicomp still manufactures Model M units using original IBM tooling
• IBM POS and commercial hardware described as military-grade in durability

The primary negatives are practical friction from aging hardware and a sharp quality-decline narrative tied to IBM's exit from consumer manufacturing. Vintage IBM products require workarounds for modern use, and no current manufacturer is seen as a true successor.

• PS/2 connectivity requires active adapters; passive adapters frequently fail
• Original Model M keyboards are loud enough to disrupt shared spaces
• ThinkPad quality declined sharply and noticeably after Lenovo acquisition
• Unicomp reproductions feel spongier and cheaper than original IBM units
• Model F keyboards nearly impossible to find; secondhand prices are very high
• Vintage IBM hardware impractical for modern computing tasks despite durability

Decades-old IBM keyboards are still in daily use — the Model M is treated as the single best example of what BIFL actually means.

The community is emphatic that Lenovo ThinkPads are not IBM ThinkPads; the quality decline after the acquisition is described as sharp and noticeable.

Unicomp gets credit for keeping the Model M alive with original tooling, but veterans consistently say the originals feel better.

IBM POS hardware was described as built like military equipment — the brand's reputation for over-engineering extended well beyond just keyboards.
