Use to use it exclusively even on 2.2. I have since moved on to Thumb Keyboard and haven't looked back
What I do love about the GB keyboard is that it doesn't use the whole screen if it doesn't need it. Something I have always hated about the Samsung keyboard is that even in the Google search widget, you click to type and !!BAM!! whole screen keyboard.
