Only every week? Every DAY here. ;)

Agree 100% here. For anything non-consumery, async serial is still
the mainstay, and likely always will be. I use serial ports all day,
every day when I wear either my embedded systems designer or network
engineer hats. The only time I generally don't use it is when I'm
wearing my programmer hat.
What's so hard about baud rates, stop bits, parity bits, and flow
control? I'll take that over the USB enumeration process any day. That
said, I am definitely a fan of USB, but when something's not working,
simpler is better, and USB is FAR from simple for anything but the most
pedestrian of consumer-level uses.
