The usual replacement parts like batteries and drives. My son hit almost 6 years but wore out 3 keyboards. Are you OK with the usual repairs?

Not one of this is durable as in what the dictionary defines as able to withstand wear, pressure, or damage; hard-wearing. "porcelain enamel is strong and durable"

For durable I move folk to Panasonic Toughbooks but those still can need a battery every few years.
