Nice to hear that they've moved the power connector from the bottom to the top.
Got two of the original ones at home (for my daughters), and the one thing that I don't like about them is they have the power micro-USB at the bottom (when used in landscape orientation). So if you're using it propped up in a case to watch a movie (for example), you can't easily have it plugged in at the same time as the connector is sticking out the bottom.
Indeed that micro-USB is the one thing that actually failed on the thing (ended up so the only way to charge it was to wedge the connector in and prop it in place with a pen), although to be fair one call to Tesco customer services had them pick up the faulty one and drop off a replacement within a few days (and it could have been the next day if I'd wanted, but I had to spend a little while with ADB to back-up what was on it first so I could easily transfer everything).
Have to say my old tablet (Nexus 7 2012) is starting to show its age a bit, so might ponder one of these myself perhaps.
