Laugh if you want, but there is a product I have wanted that as far as I know doesn’t exist. But if it did, I would buy it. I want a set of rubber dust plugs to fill up the ports I rarely use on my MacBook Pro, e.g. Firewire, Ethernet. I know this is a really pedantic idea and I’m not that precious about my MacBook Pro. But I do think there is a market for it, and I wish someone would hurry up and invent it.
