I use an Epson 740 printer and always boot back into my Classic partition when printing pictures...the options are much easier to set up in OS9 than in OSX...i've messed up several times when trying to print in OSX.
I also boot back into OS9.x when burning CD's with Toast...I have made coasters in OSX, but I can't remember the last Coaster in OS9.
I still use an older Quicken version and American Heritage Dictionary which require Classic...My Appleworks 6.2.4 application is installed on the OS9 partition, although I can run it from OSX without starting Classic .
I have several reference CD's which require OS9 and earlier to run...e.g.,ABA Family Legal Guide, 3D Atlas, Family Doctor, Mayo Family Health, GME97...be a shame to toss them.
And a Passel of different games which can only run in Classic.
I'm afraid I fail to see why a lot of folks see it as a plus to drop OS9 altogether...i'd feel shortchanged if I couldn't still use it.
