I'm just waiting for the update to Android 5 Asus slow a bit to offer.
It replaces my Nexus 7, 2013, with a much better battery life.
Note that I speak well of ME572C, not the old Pad MeMO 7: avoid the pitfalls that you will be strained as tempting "bargains".
(Why the hell Asus has kept the same trade name? Mystery ...)
