There’s PLENTY of research by knowledgeable people who consider the ipad very short of functionality.
There's plenty of research by people who consider the ipad very short of functionality who have NEVER TOUCHED an iPad... just like the people who produced the iPad is to Rock and Watermelon charts. Ignorant. Many of these same people were saying the exact same things about the shortcomings of the iPhone two years ago... and were predicting it would never amount to anything and would be a flop. It's FUD, driftdiver.
There’s PLENTY of research by knowledgeable people who consider the ipad very short of functionality.Apple is, and always has been, about minimalism. The point of the iphone and ipad is to do what you want(eg. movies, photos, mail) as fast and as easily as possible. People that are willing to go the extra mile to get all the "features" they can out of their system inevitably gravitate to Windows or Linux.
Complaining about apple devices being short of functionality is like complaining that oranges aren't apples.
