USB 2 has a bandwidth well below the 1gbps wireless connection. The thing is, I don't have anything that uses USB 3.
Funny, I just bought a new backup drive. The only connector it has is a SuperSpeed (peripheral end) USB 3.0 connector.
I've never seen an HP printer with lan/w-lan that actually works over the network without connecting to a Mac or AirPort with USB. It works sometimes or maybe just the first 10 times... And they're always a nightmare to set up.
Good point. Same with lots of low-end printers. They may have a LAN connection, but, sometimes it doesn't work right, and sometimes the mfr doesn't maintain/upgrade firmware. Sometimes I end up plugging the printer directly into the host USB port for just that reason.
If Apple had asked me, which they didn't, I would have said it needed 2 USB 3.0 ports.
