You're wrong about that one. Even now with time to catch up, there really isn't a tablet that compares to the power of the iPad. When it first came out, it was far more effective than any tablet out there.

As for iPhone, there are a lot more options, but I don't recall a touch-screen phone that was as useful and sleek as the iPhone.

These products set the standard for the industry and continue to be the metric to which similar products are compared. That's more than just good marketing there. Consider that the announcement of iPad was laughed at by many for the name and for it being an 'oversized iPhone'. If it really was crap then no amount of marketing could have saved it from bombing. But it is now one of the most successful products in the world, due in large part to marketing sure, but also due to its innovation, design, and usefulness.
