Being one of those with ICS causing display glitches and random reboots, I called Asus tech support a few minutes ago. I was actually surprised at how quickly I got through to someone. But what he said surprised me. His statement to me was on the order of "the ICS update has not been released yet by Asus for the Prime"!?!? When I told him that the firmware update was shown as available on the tablet and that it then downloaded and installed, he said that the update was "from the manufacturer -- not from Asus", and that Asus has to do some tweaking on ICS before releasing it. WTF? So now I'm really confused. IIRC, the update shown on the screen did not indicate who was releasing it, and in fact it didn't really say anything about it being ICS (I just assumed that was it, which unfortunately it was). The resolution is that they're having me RMA it to them, where I would guess their technicians will restore Honeycomb and send it back. That's OK with me, but brings up the question of how I know in the future that an indicated firmware update is an "official Asus" update or not. I sure don't want to re-install something that breaks it again. It's also scary that an o/s update could come from more than one source. Overall, though, I was pleased with the responsiveness of the (offshore) rep, who did not seem in a hurry and went over everything carefully with me. But he did not question that I had an issue and had a prepared response.
