iPad... still waiting

I've wanted the iPad since I first saw it announced.  I go out of my way to find an excuse to drop into Best Buy or the Apple Store just to fiddle around on it for a little bit when I get a chance.  The problem is that I'm cheap and need a good reason to buy one other than thinking that it's really cool.  Trust me, I've worked on good reasons, but haven't found one to justify the cost yet.  It's an incredible machine and I think I will really like the iBook feature, but that's not enough at this point.  The truth is, I'm planning to be that guy that waits in line to be one of the first to buy the new iPhone.  The advances with multitasking, an HD-Video camera, a camera on the front for video-chat, and the many other advances make this purchase a no-brainer and well worth the investment.  I'd love for you to give me a good reason to buy the iPad, but for now my Macbook Pro and  the new iPhone seem to meet all of my needs and so much more!
