I don't doubt that SD card slots and 3G radios would have made this a must buy for people, but the biggest issue from Google's perspective is the lack of Android tablet penetration. Android tablets fighting the iPad front have failed to get traction, so Google is going to Kindle Fire route: cheaper cost, quality hardware missing a few bells and whistles. Except in this case the OS running on the device is far superior the Amazon experience.
