Not only a rounded rectangle isn't narrow enough, but it is also an obvious shape for a tablet.
Infringing on an incredibly broad patent for a rather obvious shape is an easy thing to do.
>That is however very unlikely unless, as the comment at the top states, the manufacturers of said device were actually trying to copy the ipad design.
Rectangles, rounded or otherwise in the 4:3 to 5:4 range have been around forever. Clipboards, US Letter (paper), 4D / 6R / 8R / 12R (photo printing) to name a few.
The good old Galaxy Tab finds itself in that same crowded company above in terms of specific size, but closer to something like A4 paper, a Passport or the rounded rectangle of the common credit card in terms of ratio.
There's nothing novel about the absolute size or ratio of an iPad.
Only n the same way a coke bottle is an obvious shape for a soda bottle, and a BMW is an obvious shape for a car.
Hindsight is 20/20.
Let's take our time machine back to 1981:

""" Steve suddenly got more intense. "Rectangles with rounded corners are everywhere! Just look around this room!". And sure enough, there were lots of them, like the whiteboard and some of the desks and tables. Then he pointed out the window. "And look outside, there's even more, practically everywhere you look!". He even persuaded Bill to take a quick walk around the block with him, pointing out every rectangle with rounded corners that he could find. """
Rounded rectangle "portable display devices" are hardly new [1].
Now if somebody could only patent taking an idea from a movie or TV series and applying in real life. Then put that in the public domain, well, it would be interesting for the public at least with regards to being able to apply common sence with a hint of health and safty. Not like we have square eye's and retro displays were rectangular with rounded corners.
The flat black rounded rectangle is pretty unique to Apple:

Notice how the PADD does not really fit in here.
I wouldn't be surprised if Apple goes after Microsoft about the Surface design if the new tablets take off in the market, because Apple and Microsoft's patent cross-licensing agreement explicitly prohibit "cloning." http://assets.sbnation.com/assets/1292505/584.pdf

I understand that you may not agree with me as these are just things to think about, but I would really love an actual response rather than a down vote.
