I LOVED Steve as a person, his charisma like no one else. The way he could present products like it was his own, loved children. I can see no one doing that. He had a passion for Apple and the products like no one else will be able to have. I can still watch 10 year old keynotes, getting sucked into it completely.
He truly was a one-of-a-kind. I don't think I will see a person like him again in my lifespan.
However, I think Apple might have benefitted of the loss of Steve in other ways. Being more open and easier to talk with.
Time will only tell if Apple is going downhill. They surely have to get innovative again. It's like they've been stuck the past two years.
Again: The people that made the iPhone, iPad, and maybe even the iPod and original Mac is still in Apple. They are the ones we have to rely on now. And they've done it before, so I'm 100% sure they will come up with something new and great in the future!
R.I.P. Steve.
