The iPad’s decline is even more precipitous than that of the iPhone, which has recently been replaced by Android devices as the dominant smartphone operating system. what’s interesting is that the market share decline immediately followed the launch of the Kindle Fire.

Of course, these numbers might have declined as people chose to hold off on iPad purchases to wait for the new iPad, which is set to be yet another insanely popular Apple product. Apple is also cutting down on the price of the iPad 2 by $100, so that should help sales, also.
But IDC still expects Android to overtake the iPad by 2015 simply because of "the sheer number of vendors" shipping low-priced devices like the Kindle Fire.
Shipments of epaper devices were also up, likely accounted for by the $79.99 price of the new Kindle. These numbers should only grow larger as Amazon and others enter into new markets that previously couldn’t afford the devices.
