7 years after the iPad release, some of us are still trying to parse out if it is a real computer. I, for one, have given up.
Great points of the rough edges that become apparent when you seriously try to use the iPad as your main computer.
While some are deal breakers right now, I think the iterative polish iOS will continue to get will address them eventually.
However, the lack of sustainable model for big iPad Apps is worrisome. This is likely a chicken and egg problem which Apple believes will improve once more pro Mac users pick up an iPad as a pro device and the demand appears. But for now, I strongly believe his gut feelings:
From the outside, it looks like the Mac is a platform to build a business on and iOS is the place to sell your passion products.
