I have seen constant stories about iPad killers that do not hold up. Now a reputable pundit says that an iPad killer is very far from happening. Not that it is impossible, but the rational is that there is a limited production capacity for the touch screens needed and the bulk of the capacity is tied up by Apple, making iPads. It is not any conspiracy by Apple. It is a few companies that recognize that a proven market is worth a lot more than a potential market. So they reach out to Apple and offer their production. And while Apple may be a tough company to please, I suspect that there is great cachet to gain by being on their vendor list.
