Just moving my PC once saw it ping out of the socket on my motherboard!

USB 3.0 is faster than eSATA in every test you care to mention. That said, people just don't CARE about the increase as it is to the consumer every bit as the same as USB 2.0. The jump from USB 1.0 was much more significant. Much like every thing in the industry right now, it's just a stepping stone.
