Dell Latitude 3440-574
One of the few computers in the professional range sold to the general public for personal use (laptop equivalent to the one used in the professional sector for the last 6 years). User-friendly keyboard. Good battery life (>7h) for office use and virtualisation. I bought it with the expectation that it would last a long time (as opposed to the one to two years of the latest laptops). It remains to be seen whether it will still be working in 6 years or more.
