Im playing on bluestacks as well. I use facebook and can trade between my main city and the annex on bluestacks.
I would have to say though, the graphics on the Samsung Galaxy Pro Tab 12 are far superior then bluestacks.
The graphics and sound via bluestacks look and sound like a low budget computer.
The network functionality via bluestacks is much smoother then WiFi (at least in my apartment complex).
The annex city helps me overcome limitations of the global trade functionality as my level increases on the Original tablet game.
It also gives me the chance to play the game from start with more knowledge to avoid the ut-ohs of my original tablet layout.
There were things the tutorial never really let you know until it's too late.
