There have been hundreds of innovations in the world of electronics over the past two decades. I mean all flat screen TVs look the same, several phone companies copied Motorola, Nokia, Samsung and Sony Ericsson designs by the dozen throughout the 90s and 2000s. But no one was as anal as Apple about the overall look of a device, the exact cm, radii etc. The ridiculousness of the lawsuit is proven by Apple's victory only in the US, Apple's backyard. You can't tell me the
rest of the world's judicial system is not as good as that of the USA.
What this has done is opened up a whole new pandora's box where companies have now realized that they can sue willy-nilly and stifle the competition, proof being since the Apple Samsung battle, smartphone lawsuits have ramped up with Nokia suing HTC, LG suing Apple, and now Motorola and Samsung suing Apple.

Earlier at least you could have similar looking gadgets with a different OS and different characteristics, not anymore. I'm not saying a company isn't allowed to protect their IP or patents they worked so hard on refining. Hell, sue everyone if they're blatantly copying. Hardware or software similarity have always existed in the phone industry. But lawsuits for such petty issues as rounded corners leave a bad taste in the mouth.
