A consummate cabal of conniving conspirators committed to composing counterfeit credit as counterweight to con callow consumers is conjecture clouding ebay's credibility unless chronicled classically.

The biggest difference probably is the OS. My work laptop is actually really well built - a Lenovo X1 Yoga with touch screen - brilliant hardware and great keyboard. I have had Windows crash out a couple of times. On the other hand, I have a cheap Toshiba that gets a battering from the family, but I run Xubuntu on it and it has never skipped a beat. I am fairly sure that if I put Linux on my work machine, it would be rock solid, but alas, I cannot. On a more comparable note (regarding the OS), but not for laptops - I used to run Windows on my desktop which is nearly 8 years old. I switched to Linux 4 years ago on this machine and have not run into reliability issues at all.

For a durable, reliable laptop, you can't go wrong with a Lenovo Thinkpad or Panasonic Toughbook. My T520 is almost eight years old and was bought well-used, but runs as well as it did when it left the factory and has none of the fit and finish issues that often develop with aging consumer laptops. I also have a hand-me-down Lenovo Edge 15 that I use to test software and OSes I wouldn't put on a "normal" computer (it's currently running Slackware--and it's taught me that Slackware's way of doing things is definitely not for me!), and it's in much rougher shape than the T520 despite being much newer.

Avoid consumer hardware. You want something made for businesses or the military. They won't have the nice bells and whistles of higher-end consumer laptops but they work and they can bought off-lease for not a whole lot of money. Toughbooks have the additional advantage of being nearly indestructible.
