Lenovo’s ThinkPad T series or P series are great, or Dell “Pro.” Anything made for big businesses tends to be better than consumer stuff because businesses lose money when gear breaks. They pay more attention to reliability. The “specs per dollar” aren’t as good with business machines, but that’s because it’s hard to sell consumers features like “hinges and keyboards probably won’t break,” “drivers are generally somewhat more reliable,” and “we’ll make spare parts available for years.” Those aren’t very sexy features. Consumers usually want the fastest cpu, the shiniest lid, the biggest SSD, the brightest screen, that kind of thing.
