Well, Samsung did race back to the drawing board and came up with a Tab that was slim and light right after the iPad 2 dropped.
Did they already have that on the drawing board? Or did they say "That's their move, here is our counter-move"? Thats what the suit is about...and I think it's also Apple warning the other tablet makers to think very carefully before dropping new tablets that mimic whatever the iPad 3 and 4 will be. What will they be? Whatever it is, Samsung just needs to get there first then sue Apple for copying.
Again, we're talking about a company thats responding,
not getting out in front with a different design.
There was even a copy of the new smartcover for the Galaxy Tab for a while before they were forced to disavow it.
