Personally, the vibrate on keypress feature is the greatest thing ever (Nexus S), and I'm heartbroken that my fancy new ASUS tablet (TF200T) doesn't support it. Fortunately, it has a (physical) keyboard, so all I need now is a decent SSH implementation. Alternatively, maybe just Ubuntu.
As a side note, you can turn off the vibrate on keypress in the keyboard options. It's separate from the system-wide vibration settings, I think.
