"Long-term sustainable source of innovation on the iPad should have come from 3rd-party developers. Look at Gruber’s example for the Mac of graphic designers and illustrators: while MacPaint showed what was possible, the revolution was led by software from Aldus (PageMaker), Quark (QuarkXPress), and Adobe (Illustrator, Photoshop, Acrobat). By the time the Mac turned 10, Apple was a $2 billion company, while Adobe was worth $1 billion.
There are, needless to say, no companies built on the iPad that are worth anything approaching $1 billion in 2020 dollars, much less in 1994 dollars, even as the total addressable market has exploded, and one big reason is that $4.99 price point. Apple set the standard that highly complex, innovative software that was only possible on the iPad could only ever earn 5 bucks from a customer forever (updates, of course, were free).
This remains one of Apple’s biggest mistakes."
I still adore my iPad, but I can't disagree with a single criticism I've read over the last couple of days.
