I disagree with you thoroughly, speaking about this one product in particular.
A notebook is not an original idea. There's a keyboard. There's a screen. There's a touchpad. There are slots. There's hardware inside. Etc, etc.
A variation of any product is not an original idea. So if you choose to have a thick product, or a thin product, or a more square-shaped product, or a product made of aluminum. There's simply no originality there.
So what did Samsung do? They took the idea of a laptop, and made it thinner. It looks nothing like a Macbook Air: It looks like an ultra-thin PC laptop. If you believe it's a rip-off of the Macbook Air, then I guess you'd also have to believe that since Apple makes a touchpad mouse that no one can do that; or that since Apple uses magnets in their power cord, that no one can make use of magnets in cords (which, sadly, the part about magnets is true due to patent laws... I think the magsafe patent is rather ridiculous... they were first to do it, but come on... we all know what magnets can be used for!... too simplistic).
Here's my personal view on the matter:
- The Samsung laptop depicted looks decent... but they didn't get the look right. And why did they not get it right? They didn't get it right because they basically took a regular notebook, squished it down to pancake size, and threw in some metal. They would've been better going with a simplistic design as Apple chose with the Macbook Air: However, in that case, people would start accusing them of really stealing Apple's ideas. But how could that be stealing an idea? Going with a simpler design? I mean, again... that's not an original idea.
- The Apple Macbook Air is undefeated in the market currently in terms of appearance, and price-to-performance when pitted against its exact direct competition for ultra-thin powerhouse higher-end notebooks.
