Not going to lie, I had hopes... and my hopes were surpassed.
I was running Tiamat and reverted back to out of the box, got the updated 3.1, and uh, wow... Absolutely NOTHING against Tiamat as it is hands-down fantastic work, which I applaud and look forward to the development, but with rebooting and random lag, I had to try stock to see for myself. Obviously this could be user error, but I was running 1:1 with no over-clocking and still would get random reboots. Not often, but often enough I took notice.
3.1 is a beautiful update, much like the major updates to the phones as the OP stated. It's taken my sluggish but awesome stock tablet, and completely ridden itself of the sluggish activity. This is damn near perfect. Obviously not, but damn!
The future is looking brighter than ever...

And with Tiamat still in development, things can only get better! Hell yes for his update!
