Should a 7 year old Macbook Air have a faulty topcase?

Does anyone have an answer?

Coddle it less. Macs don't need pampering.

Have an answer to what? Two computers, out of all the computers Apple has sold are, by themselves, indicative of nothing. From that limited data set, it's not possible for any of your fellow users to comment on the overall durability of Apple products.

I can tell you that, other than my Powerbook 100 that up and died when it was a couple of years old, I've had one problem with a Mac laptop that I can remember. It was a defective screen that was covered by warranty.

However, I would point out that putting anything on the keyboard of a Mac laptop and then closing it is a recipe for trouble. To make the device as thin as it is, there is no space between the top and bottom when it's closed.

I can't believe that I have 15+ year old Windows laptops with no hardware problems and I've had 2 Macbook Airs with 1) a screen problem and, now, 2) an expensive-to-fix topcase problem. WT*?? Is this the norm for Apple? I get that as computers get older, memory, speed, etc are limited. But the basic hardware? For the record, it's the Apple genius bar diagnosing my non-working keys problem as needing a new topcase. This computer has been coddled - dust cover on keys, foam-padded carrier for the occasional travel, never dropped or hit or spilled on. For the cost, this should be a superior laptop, on par with the best, similarly-priced non-Apple laptops. Apparently, not. Does anyone have an answer?

Maybe your use of a keyboard cover facilitated or contributed to your issue:
