It's not just as aesthetic addition it makes the iMac more durable.

Given that families are a big market for iMacs it seems to be common sense that you would make it as kid friendly as possible. Last thing you want is an errant toy to destroy your screen.

How ironic that you mention reliability as an advantage of a mostly unserviceable all-in-one.

Serviceability has nothing to do with reliability, for one.

They're designed to not be serviced by anyone - not customers, not retail staff. So, they have better quality parts that reduce return rates, and get replaced by new or refurbished units if they are lemons. Nothing wrong with the advances of mass production.

If the machine is as unserviceable as you claim, then the increased reliability is indeed an advantage (or at least a mitigation). I'm not sure I see the irony.
