They're not the "present". Not by a long shot. Too small, too weak, too stunted to be the present. Future's bright, though.
You're taking a portion of his quote out of context. Put back the "It's where the money, excitement, consumer interest, developer interest, corporate interest, education interest is, etc."
I also think you're being pretty shortsighted. Even today, we have desktops in spite of having notebooks. We have workstations more powerful than desktops. Servers more powerful than workstations. Mainframes more powerful than servers. Supercomputers that wipe the floor with all of them. There will always be applications that need more power. When you need to step up to the next level.
But we still have many, many more notebooks out there than we do workstations. More servers than mainframes. More servers and mainframes than supercomputers.
And today "mobile", iPhones and iPads, are outselling MacBooks and iMacs by a huge margin. In fact, at the iPad 3 announcement Tim Cook revealed that Apple sold more iPads in Q4 2011 than any individual PC manufacturer sold of their PC devices in the same quarter. Double that when you include Androids.
The future is here, today. And if your sole criteria for denying that is the fact that you can't create an iPhone app using an iPhone, then you're missing the point, big time.
BTW, people are recording music on iPads. Professionally. And sketching and designing new products. And as to "make a feature film", Olive and Night Fishing were shot entirely on iPhones. As was a portion of the Avengers film.
