The simplicity and reliability of RS232 is still mostly unbeaten. I would love to have a dedicated RS232 port on my notebook, but besides some rugged monstrosities, nobody is building them anymore.
Regarding this mess of "legacy" ports... Besides most DV and other semi-professional video equipment, Firewire was only really supported by two vendors: Sony, calling it iLink for whatever reason and Apple. It was only useful in the time frame between USB 1.x and USB 2.0. Features like direct memory access are now considered a security nightmare and I'm actually glad it almost completely went away.
Personally, I'm hoping that USB 4.0 will be around rather quickly and will kill the Thunderbolt nonsense of Apple (and Intel). USB 4.0 will finally even have the capability to replace the mess that currently is HDMI v.s. DisplayPort. Also, it promises to be backward compatible with all previous USB standards, at least on the protocol level.
Imagine: One type of port to connect ALL your peripherals. Sounds like a dream, doesn't it..?
The next step would be to harmonize all those wireless standards: WiFi, Bluetooth a whole bunch of proprietary implementations and maybe even wireless USB 4.0, all clogging up those few little bands of "unlicensed" spectrum.

quote: Chris Slycord I wasn't aware. I assumed it could passthrough direct control of the device, without having a driver for it. My bad.
Actually, both is possible, depending on the implementation. e.g. under OS X, you could have a native supported USB-Serial adaptor which establishes serial ports for OS X. These ports could be forwarded to a VM running windows as COM-Ports. But you could as well forward the Mac USB-Ports to the VM and install windows drivers for the USB serial. One or the other variant could work or not, depending on VM software, driver robustness, USB adressing scheme, etc.
