5) The Efika serial port seems anachronistic now, especially since the PS/2 ports are gone. Can it be done away with in potential future versions of the Efika, so that something else can be put there?
As phx said, a serial port is fairly important.
Remember the EFIKA isn't necessarily going to have a graphical head. Actually, I thought it would make a good high end ADSL router, using a PCI riser and an ADSL card. In this case, a serial port is vital for configuring the firmware.
USB is horribly complicated to configure before you get to attachment - and remember, USB hosts don't connect to USB hosts. You have to initialise the port, enumerate connected devices (and cope with hubs), and then you'll need drivers for the cable to connect to another host. All of these things are way overboard if you want to spew out a few "hey, I'm alive" messages to a debug console.
Many devices that don't have a physical serial port often have headers (even if they aren't connected to anything) on the board for either RS232 or TTL serial. In more recent years, USB host controllers have a "debug port" mode that acts like a dumb serial port, removing the need for the legacy serial port. Its public usage isn't very common, though. LinuxBIOS has been using it for modern chipsets.
The serial port has lots of valuable life left in it
