A shady company in China has just the solution you're looking for!
This iPad knockoff might look relatively legit, but it's actually running a hacked version of Google's Android phone OS modified to look like the iPad OS. On the inside you've got a 600MHz ARM CPU instead of Apple's 1GHz A4 processor.
Otherwise, who knows what's inside? But hey, it's a mere $150, much less expensive than the real deal, so maybe it's a better option! Then again, maybe it isn't.
