I let mine sit after plugging it in again, and it was stuck in the boot animation for 30+ minutes. Unplugged it again, let it stay unplugged for a couple minutes, plugged it back in, stayed in boot animation for another 5+ minutes before I unplugged again. I guess I'll try it again tomorrow, but I imagine it must be dead, so I'll have to contact Google and go through the hassle of returning it and waiting for a new one. Given my "luck", I guess I shouldn't be too surprised. v_v
