No, probably never...
The iPad performs no function that I need or want, what I have already is more than enough. If someone was to hand me one tomorrow, I wouldn't know what use to put it to. The admittedly aesthetically pleasing combination of plastic, metal and glass would probably end up gathering dust somewhere, or being sold on eBay.
I don't see the point of the whole tablet form factor - every such device that I have encountered so far has remained almost permanently docked. In a tech lab these things may seem wonderful but in the workplace they are almost a hindrance to my productivity. At home, I just cannot see where the benefit would be over a laptop or netbook (please don't say I can use it to surf the internet from the toilet seat). The textbook thing doesn't appeal either, the only time I need information on the go is when I am at work and my iPhone does this well enough for me.
The iPad is an unnecessary expense and a mostly useless consumer oriented toy.
Of course, this is just my opinion, based on what I have read. I reserve the right to change this opinion without warning and without giving a rational reason. A change of heart may occur after I have played with an iPad for some time 😀
We'll see how things are in a couple of years...
