There was a suite of android-based tablets. To be clear, if you like Android or kindle tabs, knock yourself out. My argument was over what constitutes "superior".
Samsung Galaxy Tab, for instance. (The one Apple sued over. Which was not because of similarities and appearance, despite the Apple-hater crowd insisting that it was, helped by Samsung. It was because Samsung helped design the iPad, and had inside information about its workings, then split off and came out with its own.)
