I got my Nexus 7 and it's charging. WOW I can hold it in one hand! It's that slim! Try doing that with the HDX. It's a little more weight than the HDX but the form factor makes it easier to hold without a cover. I have little hands so I am really liking that part.
It's charging now. WOW that is one short charger cable! Please someone tell me a longer alternative.
I will give it a thorough inspection later when it's done charging.
