It turns out the Mac Mini doesn’t support dual monitors. That bites. So much for that clever (and relatively inexpensive). Back to the drawing board [boy hies off to fetch credit card and re-up virus definitions for PC, since it looks like he’s stuck with it for awhile yet].
I do know about the Belkin USB Flip, and that’s high on the list of solutions to my on-going fascination with two monitors, but that still leaves me with a PC. Hmmm, must investigate if some flavor of LINUX works under the Flip-mode.
