I would say the real transition was when they switched to Intel! They really are an amazing company!

It is really interesting. Basically, the tablet is what "personal computing" was always imagined to be, but has never been successful. People don't even realize, that Apple being successful with iSlate will LITERALLY be Apple reversing the entire history of personal computing to its original intentions in a sense! And all of it is possible because of this MASSIVE and TOTALLY COMPREHENSIVE product strategy and ecosystem that Steve Jobs has put in place piece by piece for decades! It is really incredible! The ability to do this all centered around culture and art/media with such a clear vision really gives me respect and admiration for Steve Jobs. Yes I know the man is a bit odd and not perfect, but there really is nobody else like him. He is very unique. More than I could EVER say for Bill Gates and others!

That is why I like Apple, even though they are not perfect as no company is!
