The only Google sanctioned "tablet" from that time was as you mention the Galaxy Tab. The only reason it had the market was because it was essentially a big phone. In Europe, you even pop a sim in it and make calls out of the box. However, the others were not sanctioned thus hardly qualifying as a "generation" and even the Galaxy Tab was discouraged by various people involved in Android development.
