Actually the iPad isn't even expensive
Starting at $499US for the barebones model, it's not exactly cheap either. That's going to be at least $699AU out here; I could buy two Netbooks at that price and have some change left over.
If I bought an iPad, it'd really just be for the sake of it, because I don't know what it's for. It's a bit too big to be portable, and there are far better surf-the-net devices, and far better gaming devices, that you can buy for a lot cheaper. The iPod Touch I can understand, it's small enough to fit in my pocket, but I don't know what the point of this thing is.
