So what can SB232 do, what is it good for?

On most new laptops, there are no serial ports nowadays, or in the best case, there is one. That is often insufficient and that is where the USB to serial converter comes in. SB232 is an ideal companion for field application engineers working on often expensive legacy devices. These devices and their laptops have to be protected from ground loops too. Most USB to serial converters fail on that due to missing galvanic isolation. However SB232 offers full galvanic isolation while being powered from the USB port. Being put in anodized aluminum box, it is also very robust so it won't matter if you drop it by accident.

Virtual COM port principal - A standard COM port appears in your Windows OS

SB232 offers full RS232 line - all RS232 signals are transmitted and connector pinout is identical to a hardware COM port on a PC. Windows drivers also allow you to set parameters to sped up the data transfer and alter the handshake signals. But default values are sufficient in most cases.
