I like my iPad and I have said on a few occasions that it has plenty of power to replace my netbook in many instances. The only thing I don't like about it is having to look down at the screen most of the time.
A iPad loving geek has taken the shell of an old iMac computer and turned it into a very cool iPad dock. The rounded bottom has a metal arm stuck in it that holds the iPad on what appears to be a custom acrylic holder.
A charge and sync cable runs to the iPad, presumably to keep it charged up and a Bluetooth keyboard lets you type comfortably. This setup would make a very nice little nettop.
