Thanks for all the comments. More than I ever expected.
I’d like to make a general reply to many of the comments posted here.
As I clearly stated at the start of the article, an iPad is all many people need. It CAN be a Mac replacement for some users. For all of you that said this describes you, I’m fine with that.
On the other hand, some users are content to stay with an iMac (perhaps with an iPhone) and never get an iPad. That’s fine too.
I never meant to state or imply that the iPad NEEDS TO or SHOULD replace Macs. No one is forcing anyone to make such a choice. The iPad stands on its own as an alternative device. As of now, Macs and iPads overlap in function, but do not completely duplicate each other. As such, both can be welcome in the same home. Such is the case for me.
In many homes, the Mac may sit unused much of the time. But it’s still there for when you really need it. Great.
All of that said, not everyone who would like to own both an iPad and a Mac can afford to do so. It’s a luxury that is out of reach for some. They will eventually be forced to make a purchasing choice, deciding which one is the better device to fly solo with. A major point of my article was that, for users like me, choosing to go solo with an iPad is all but impossible now — no matter how much I otherwise like the iPad.
My hope is that this may change someday. It was in this spirit that I detailed what it would take for an iPad to function as my primary/solo computing device.
Similarly, I believe that, over time, Apple’s two product lines will converge. I’m not sure how long this will take, maybe as much as a decade, but I don’t see Apple indefinitely maintaining these two product lines as consumer devices. Assuming this is true, I am confident that the iPad is the primary direction Apple will wind up going. Given this, my article was similarly meant to suggest what iPad limitations I hope Apple will address as it moves in that direction.
