There are two kinds of laptops on the market, consumer laptops and business laptops.
It seems that companies try to market business laptops as having better build quality, better durability, etc.
But I have spend a lot of time and I have found no actual studies that confirm this claims. There are only promises from manufacturers not backed by any hard evidence or lab studies.
I think it would be very valuable if notebookcheck could write an article about that.
Can you ask manufacturers about what design standards are used for consumer laptops and for business laptops?
For example, are hinges more durable, e.g. are they designed to withstand more open/close cycles?
Can batteries take more discharging cycles? Are screens of better quality?
Are they build/tested for accidental drops?
I am not sure about that as it seems that nowadays even the cheapest consumer laptops have passed MIL standards.
So what really makes business laptops different from consumer ones?
Maybe business laptops category is just the same quality as comparably priced consumer laptop
but only cost more due to better warranty terms, better customer support/faster response times, better availability of spare parts, better security features?
