Interesting and makes my battery life testing of two hours plus streaming movies by way of NetFlix or my home media server look great.
I managed to get away from the AC 120V short cord by putting together an alternate DC power supply/ charger.
Viewing angle has not been an issue to me but then I have not tried sharing the view with others standing beside me either.
I have a combo case / keyboard that I have been using as a case and stand but as yet have not tried the keyboard as I read one post where it caused the touch screen to cease working and I really do not do a bunch of typing on it anyway.
Thanks for posting the link.
