Solid specs check off most of the key items in RAM and storage, cpu (7th gen vs current 11th gen). And Latitude business-grade laptops tend to be solid, much more durable machines.
But it remains tough to swing $530 for a refurb off-lease laptop, especially with a 90-day warranty.
When similar but not quite as nice specs can be had for around the same money, admittedly in a consumer-grade brand new laptop. (8 vs 16GB RAM, 256GB vs 512GB SSD, no touch screen - who cares on a non 2-in-1 laptop.)
