I think the most impressive demo for the ST line is More or Less Zero. Unfortunately it's STe only, so won't run on your machine. I have recently got myself a 1040 STe with ICD's the link SCSI cable and a 40 mb external SCSI HDD. I've never used an Atari in the back, I found the OS very primitive. No command line, no multitasking, very little you can do with how the OS looks (that green is just plain ugly). Primitive but it has a charm to it I'm tracking with musicmon atm, and playing Curse of the Azure Bonds The STe is nice cause you can use three channels for chip tunes and two for digi samples, you can make SID like tracks with better drums (digi).
