Samsung has vowed revenge over Apple's recent lawsuit against the electronics maker that claims Samsung "slavishly" copied Apple's iOS devices for its line of Android-based Galaxy smartphones and tablets. Apple is reportedly miffed at Samsung for taking technologies and design ideas such as organizing application icons into grids and making smartphones with rounded corners. "Rather than innovate ... Samsung chose to copy Apple's technology, user interface, and innovative style in these infringing products," Apple argued in its filing. Samsung isn't taking the charge lightly and says it will "respond actively to this legal action," according to Agence France-Presse.
