If I was a mac user around the time the 6100 came out I probably would have purchased a new discontinued 950, 800, or 840av instead. The only thing the PPC had going for it when it was new was a kick butt FPU, which most people didn't need at the time. Remember that all the software that was out was 68K anyway, would take a long time for PPC native code to come out and take advantage of the PPC chip, and by that time PCI Macs would be out anyway (cheaper too I think).
