Apple made a significant number of tradeoffs to reach $500, but for a budget user, they're reasonable tradeoffs.
Even after years of operation, they'd be a decent buy on the used market compared to comparably priced windows laptops that would literally fall apart at the hinges and overheat.
As a Linux/windows user I was completely baffled that you actually have to click (at least in the default setting) to make a mouse click instead of just giving it a tap. Does anyone prefer that?
