I do not have an idea if Jobs had a technological vision. What I know for sure is that while he was a douchebag, he had charisma. He lusted for perfection. He was maniac in what touched organisation. He managed to get people doing what he wanted. He had presence. He had something that definitively captivated audiences. Now, the last WWDCs have always have some major glitches. Heck, either it was them crashing all the time, or in the last one, not putting on time the current one, and the web site broadcasting the new, and Apple TV the one of the year before. Timezone glitches? (...) Especially in the last one, my wife was saying all the time...my God, are THEY ALL GAY? ...and ending that launching the Weekend from San Franscisco...amauteurish. Women seem to have a more developed eye for that. Honestly I used to come on as soon the job allowed me too to see WWDC live events, now excuse me...Gay pride has a corresponding event, and bands are for MTV. I wont be hurrying up to watch more WWDC events. Will read about them in Mac Rumours. About buying Apple products...I see no match for the iPhone, however may next notebook may run Linux.
