Mine is fine so far, agree with the power supply issue, mine hasn’t fallen out yet but it is a bit fiddly.
I’ve done the Win 10 1511 update which went smoothly and am currently installing a Windows Baldur’s Gate Big world Tactics version, which may not be familiar to you but is a good stress test as the X16 has been running constantly for the best part of 20 hours doing the install with no issues so far.
Android is not great, Google play doesn’t work so I will need to root this sometime this week.
