Android tablets can demolish the iPad with this strategy
Bring some really good exclusive GAMES to the platform. I'm talking about doing something drastic here like paying Blizzard a few hundred million dollars to bring a scaled down version of Diablo 3 to Android tablets exclusively (for mobile) or paying Valve to port the source engine (along with TF2/HL2/L4D) to Android.
Furthermore, they should preload these games (or at least demos of them) on the upcoming $200 tablet. Every gamer out there thinking of getting a tablet would instantly pick the Nexus over any iPad.
