Problem is they're finding out those cheaper tablets are pretty good and have more features. So they're not going to drop 500 on a tablet when a Samsung Tablet fits their needs.
But haven't the other tablets been having trouble picking up traction too? If the ipad decline is a speed bump, the others are a 20 car accident with multiple casualties.
Its not like there has been one clear replacement for the ipad that's stealing its sales. The tablet market as a whole is on a decline, I thought (could be wrong, feel free to correct)
