To each their own.
I have an iPad2, iPad3, iPad mini, iPhone 4, and tomorrow, a 5s. The iPad's are in constant use by our family. I have a lot of digital kids movies on iTunes that they watch. Heck, I even have some of my movies on the iPads. When we travel, they are a god send. With an extra HDMI cable and the iPad connector, I can watch my movies in any hotel room across the country. Most Kid's apps are free to $4.99. Once they get bored of it, I have no issues deleting them. MS programs and games are hitting $50 each. When apps are so cheap, its a no brainer which one I'm going to pick.
They are lighter than my laptap so now I just use an ipad and keyboard at conferences. We even got a MiFi so we can have wifi service for all our iPads when we are out of the house. We use them to read ebooks, surf the web, watch movies, play games, etc... The larger screens make it so much easier than staring at the small iPhone screens. In fact, I just gave my "new" netbook to my father-in-law because I haven't touched it in over a year.
If you thought that coming to the iPhone forum instead of the iPad forum would get you flamed less, you're obviously wrong. Obviously you have no use for an iPad, so why even bring it up? A less flammable post would have been "Are there other uses where an iPad would be more useful than an iPhone?" Same idea, less flame, and in the proper iPad forum.
