An argument which would have held water were Samsung producing such tablets prior to the iPad selling millions of units. People know the iPad industrial design as the iPad, not "that thing that looked like the thing from 2001."
I'd have loved to see prior art on the USB connector. That's the most shameless part of all.
It's completely needless – the dock connector only makes sense in light of Apple's larger ecosystem. Why not use micro or mini USB, like everything else on earth?
