Thanks for the "prodding", RtC! Just finished D/L'ing and installing X11 & OpenOffice. Launched and ran fine on my FrankenMac 9600/G4/400. I'm pleased as punch. Going to take this beast into the office over the coming weekend and test printing on the network to a couple of laser printers. I'll post results.
On the titled topic,
ImageMagick installs via Fink and requires x11. I used it to batch convert a directory of 16-bit black and white tiffs from my scanner to jpegs, with a simple csh script.
GnuCash is a great quicken-like program - seems very stable and handles imported QIF files from my PDA nicely. I wonder if we'll see X11 apps in the next "Power of X"?
X11 starts up a LOT faster than XDarwin; its now a candidate for "Login Items".
