Samsung didn't make just any phone, they copied the iPhone.
Microsoft at least managed to try something completely different with Windows Phone, and I think it's a hell of a lot more innovative than what Samsung did.
Explain, in detail, how they copied the iPhone? They look similar, but so do many of the other smartphones out there. When you say they copied the iPhone, I expect to see pretty much an exact copy. If you want to jump outside of the Apple fanboy camp for a second and look around an electronic store – you'll see all kinds of electronics that are almost 100% the same as the leading competitor. Laptops, TVs, MP3 Players, Washers & Dryers, Fridge, Stove – you name it. Then take a stroll down the Entertainment isle and point out an original movie.
