No mine is not good, the menu button goes nuts when I take the tablet in my hands.
I have a partial solution to this; there is a registry entry that blocks the windows key. It works for both keyboard key and the touch key. However random vibration is still there, and is totally unnacceptable.
It’s funny because I don’t need this stupid button for anything. I could probably also live with blocked windows key on the keyboard. But the constant vibration is just too annoying.
I’m going to send it back most probably. I guess it’s better to speend a few hundreds $ extra and get something working out of the box or get a local service if not…
