No better or worse than most other tablets, I've found. Yes, keys are disabled when the cover's folded back. I haven't done any scientific testing on a threshold, but the on-screen keyboard will pop in/out as you flip the cover in and out of position. It also engages the rotate lock when the keyboard is out, for obvious reasons.
