The only thing I boot Classic for is... oh yeah. Nothing.
I have Photoshop installed, but I use it so rarely that I almost never boot Classic. I've been planning on doing the Gimp thing (I'd rather use freeware than pay for the X version of Photoshop) but I haven't gotten around to it yet.
simX, do you already know about 6.2.4 for AW? I'll assume yes, but thought I'd point it out while I am posting already...
