Well, what I'll say is that the iPad, and indeed tablets in general, are still a pretty niche product, at least for now.

So far, in my everyday life, I really haven't came across many, if any at all, situations where I told myself "damn, a tablet/ipad is exactly what I need right this moment".

To me, the tablet/ipad is kind of like a device that is pretty average at a lot of things, but really doesn't excel in any.

For pure productivity, it doesn't beat your desktop.

For portable productivity, like giving presentations or typing e-mails when outside of office, it doesn't beat your laptop/macbook/whatever.

For pure entertainment, it doesn't beat your console/PC/home theatre/whatever it is you have at home.

And for pure portability, it doesn't beat your smartphones which can fit inside your pocket and can be operated with 1 hand while standing/walking if you choose to.

So really, to me, the ipad or tablets in general are mostly products that you use due to the novelty factor. Sure, it has its uses and advantages, just not very compelling ones.
