Very ugly but luckily you don't look at that part much on a laptop. Especially on macs, the rubber feet just fall off and the case ends up scratched and marred up overtime.
Yeah I have a 2012(?) and one of the only things is that the feet have all worn flat and smooth, and feel like they are going to fall off. And if I want to overthink it, it's probably one of the cheapest feeling things about it.
What do you mean the rubber feet don't stay on? They make millions of these, milled out of aluminum, they can't keep the feet on?
Personally, I would trade a lot of design elegance for some hardy laptop feet.
