One thing is just the significantly higher latency on consumer/business Internet connections. ISPs all optimised for bandwidth, not latency. They don't market latency. This is thanks to things like packet interleaving. Back in the early 2000s it wasn't uncommon to get a sub 10ms round trip to a server in the same country. Now you'll be lucky to get sub 30ms. So we get things like HD video of the person's head bobbing around, but can't actually have an enjoyable conversation with them.
