I think you reached a different conclusion than others reading the article which may explain the confusion. What I took away here is Gruber thinks it will be unlike other tablets that have been released due to Apple's strong focus on practical usability and their ability to tightly integrate their hardware & software platforms unlike other companies who have attempted tablet computers. As for the authors credentials -- he makes a living covering Apple. He has an excellent understanding of Apple's corporate culture and a good feel for how people are using technology in their everyday lives.
