I think the emphasis should not be on the hardware, but on the package. True, it used USB (like the PowerMac G3 before it), but at that time this was just a faster replacement for the ADB bus that Apple had used as an universal bus before, and SCSI had been replaced by IDE as an internal connector before.
The major point of the iMac was the "just works" philosophy, as pointed out in some Apple ads that had a kid set up the iMac including internet access in a fraction of a time a HP engineer could do it with a PC. It was all about reducing the complexity that network access, multimedia and all the other nifty features had brought to computing during the last years. And that theme stuck with the iPod and the iPhone and is now widely regarded as the best way to bring technology to the masses.
So it was a revolutionary machine, just like the original Mac, and the hardware was the smallest part. I still have the original box, maxed to 128MB RAM and running MacOS 10.3. Just in case, because it "just works."
