Seriously, who cares how many cheap tablets are sold? The people who buy these cheap tablets were never going to be Apple customers anyway - Apple haven't lost anything by this as they don't market to this demographic. What matter is Apple continues to take the lion's share of the profits in the phone and tablet market. It means they have the cash to continue R&D, and forge ahead whilst everybody looks to them for direction.
