There were several considerations:

1) Many of our customers have older computers with RS232 ports and not 
USB ports.

2) USB -> RS232 adapters are readily available and inexpensive.

3) We didn't want to get into the USB driver support business. We'd 
rather let the companies that make USB -> RS232 products have all that 
fun :-)

Yes.

The K3 design is modular, and the digital I/O board has been designed to 
be replaceable with a USB-based board if we decide to offer one in the 
future. Or an Ethernet-based interface, or...
