iPad Prediction/Concerns

I predict that in three years, every member of my immediate family will have an iPad. This seems like something that is really going to take off in a similar way that the iPod did. However, I do have some concerns with the iPad. First off, it has no keyboard, which is somewhat annoying. Also, it's too big to really be your iPod–it's more of a computer with iPod capabilities but you can't really take it with you when you work out. Finally, the whole reading books on a device like the iPad (or even on the Kindle) is completely lame! Books should NOT be read on a screen–they are meant to be in print!
