275MB update specifically addresses stability of the system while docked
Asus' Transformer Pad 701 has a 4.3 Jelly Bean update pushing right about now. The 275MB update boosts the version up a number, and specifically addresses stability and performance of the keyboard dock. You'll need to restart a couple times to get all the dock updates according to reports we've received.
You also might want to hold off for a little while on this one. Everyone wants Android updates, but as we've seen before, they don't always make things better. We've seen several reports of tablets being locked awake draining the battery both while docked and while free-standing. While these may be random issues, dismissing the update notification for a day to find out may be the smart thing to do. If there is a problem, we'll be sure to let you know.
In either case, the forums is the place to discuss this one.
