I'm pretty sure that the original idea was that 10Mbps was PLENTY for 'lots' of systems to share. And so it was for a long time. Some of the early ethernet TCP systems I worked with managed about 60kbps, and I was happy when I improved that tenfold to 600kbps... Since most internet usage these days is web access, and there is likely to be a slow (1Mbps or far less) bottleneck in there somewhere, you probably won't even notice if your USB frob is limiting you to 1Mbps. I have a couple USB1.1 wireless links, and they work 'just fine.' My how times have changed. Still, I'd be surprised if there aren't differences from one USB Enet to another, and/or comparative benchmarks out there somewhere. And a USB ethernet is not the thing to get if you're after maximum performance.
