Hey, I have a PowerBook too, but don't say you're limited to one serial port. You could use the desktop bus, and there are extenders available. I do agree that a parallel box wouldn't do me much good on my Sparc. For a while, my IPX was my "portable" computer, albeit with monitors on both coasts. But the box itself is quite lugable. If I wanted to, I could plug it in along the hallways of airports and use a palmtop with a serial connection to read mail and up/down load ... /jordan
