What are the do's and don'ts pro's and con's of using usb to serial (9-pin)??

Pro's:
It adds a serial port to your computer.
Quicker and easier to plug it in than a screwed d-sub connector.

Con's
USB port provides 5V max and not much power, serial comms may not work well in some cases.
Requires device drivers to be loaded on the computer, there may be compatability issues.
