I put a "GPIO port" on the first SBC I built. I'll probably have one
either as a debugging port or a geek port on everything I design for fun.
A parallel-style port really is a nice thing for prototyping and
experimenting, especially in this day of everything being high-speed LVDS
serial everywhere.
Don't get me wrong, I -like- that we're getting reliable high-speed
peripheral buses. However, there are a lot more folks who can go from
"neat idea" to "cute widget on the desktop" quickly via a parallel port
versus USB. For one thing, there are very few through-hole USB
interfaces.
Again, no, Joe Consumer doesn't need a parallel port. He doesn't need it
any more than he needs a quad-core processor, 3GB of memory, hundreds of
gigabytes of disk space, or a gigabit network port.
