I was referring to the form factor and appearance (which is what Apple tries to have an issue with other tablet makers like Samsung), we are not talking about the specifications or external addons like pen, keyboard (Asus Transfomer like) or hidden internal HDD.
So essentially what you are saying is that if the Samsung Tab had come out with a pen, an internal HDD/SSD and detachable external keyboard that Apple wouldn't have claimed it was an iPad "clone"? The main thing Apple is arguing about is the form factor and rounded corners even to the point of fiddling photos to make it look like the same size aspect ratio.
The point is there have been loads of previous prior art devices released that had the same or very similar physical form factors as the iPad/iPhone even some with a single central button at the bottom. Apple should just move on an stop nit picking and suing over stupid things like this just because they don't like competition.
