Oh no! Trapped by a device that's too useful to put down?
It seems like the issue for many of these folks is that they can't resist firing up a game instead of working.
So maybe the solution is to delete the games.
Or do as they seem to feel is proper and keep the iPad only for "playtime" and train their brains that work is on computer, fun is on the iPad.
Which is fine. So long as they keep the preaching that no one can do work in an iPad to themselves. Because that is bull. It all depends on what 'work' means. And despite what Mr Ballmer thinks, it doesn't equal using Microsoft Office. I do 12-16 hours of work, six days a week a good 36 weeks of the year just fine with an iPad rather than a computer.

but the average person reliant on his computer for productivity will never rely on his/her iPad.
On the contrary, I think if you asked the average person what he or she does in a day you would find few things that can't be done just as well on an iPad or similar tablet. Because for the average person about all they do is check email, perhaps play pandora in the background etc.
The people who spend all day at their computer typing novel length reports etc are not average any more than I, who spends all day on film and TV sets, is average.
Use what works do for you but don't presume that you are the touchstone of the world and its needs and **** on folks that have a different view and things will go just fine.

The answer to your concern is self control - that's it. Beyond that, current tablets will never be desktop or laptop replacements. Perhaps in coming years when they are considerably more advanced than the toys we have now.
So will they or won't they. You just say they will never be, and then said maybe in a few years.
By seriously, there will always be a few tasks that will need a regular computer. But those will be the non average things. Tablets will get more powerful and folks will be more accustomed to them. In a generation or so I think we'll see computers go back to their original roots of labs, etc and creatives like my company and the average person will be rocking personal devices. So they might have a computer at home but it will be more of a hub for storing backups, media for their connected TVs etc. the computer won't be THE thing they turn to for really anything. And that I what I think Tim Cook was saying with his Post PC world comments.

It is iOS itself that is not as well suited as a desktop OS for a number of tasks. For one thing, when I have a 22" monitor at home and a 24" monitor at work, I don't want to be using a 10" iPad screen to get work done.
Which has nothing to so with iOS.
