Well got unit 3 today. Unit 3 would bounce up and down on the mass storage mode when connected to a Mac. I unplugged it from the Mac and plugged it into a Dell. Bouncy there too.
It won't stay up long enough to copy files into it.
I am speechless at this point. I can not comprehend how they could possibly have sent me three iLiad's and had each of them die in the first few hours, all with different failure modes.
