Unless it's HEAVILY optimized over the desktop version,
BlueStacks has an incredibly long way to go.  I don't know if
it's poor emulation or if it's just a super complex process, but
my computer (which could probably power a small country) runs
most apps from BlueStacks so poorly they feel like trying to
code in Eclipse.  Slow, unresponsive, sluggish, lethargic, and
any other adjective that means "takes forever to respond."
