True, but this requires excluding the Firewire from the listing. My main complain is the inaccuracies, which I partially addressed above.
I even ignore USB 3.0's expanded and incompatible cables - you can't plug a USB 3.0 cable into anything that doesn't support USB 3.0. You can plug USB pre-3.0 cables into USB 3.0 devices though. The saving grace is that USB 3.0 cables are rarer so you're far more likely to pull a USB 2.0 cable than a USB 3.0 one.
This is misleading, considering that you can indeed use a USB3 cable with a USB2 host. And as stated above, you can use the old cables with new devices, so I would not exactly call this an actual change of standard. Upgrade it is. And personally I much prefer the idea that you can use any cable, not a proprietary one.
