It might useful to mention that I hope to occasionally use a full-sized keyboard on my laptop. I can already drive an external display and have a PS/2 port for a mouse, so the keyboard is the only peripheral left to make the laptop. I could try a USB keyboard but it's interesting to use a USB to PS/2 adapter as I have a KVM switch at work that's based upon PS/2. Otherwise, for home use, I might consider a USB keyboard. I'd also like to use a USB-based CD-RW and USB-based external HD. As you can see, all of the above hinges on getting a working PCMCIA USB card.
