Yup. And I've got my USB (A) to DB9 serial adapter handy.
Which is unreliable in many situations. I worked on several projects that had issues involving intermittent data loss on a DB9 port, and every time the culprit turned out to be a USB/DB9 adapter. When we'd install dedicated RS232 cards, the problem went away.
For laptops, the answer to this kind of thing should be a standard space where a customer can specify what ports he wants... you get X number of standard ports, and then you can choose what goes into one or two available spaces. But you're just not going to see that happen with manufacturers, even if the customer is willing to pay a greater cost.
