Two former enemies are now working together: Apple and International Business Machines Corp, known more commonly as IBM, have joined forces to create business apps and sell iPhones, as well as iPads, to corporate customers. For IBM, it will allow an expansion of its business software through popular mobile devices, which could help their overall revenue. Apple famously went after IBM with their iconic 1984 commercial, which remains one of the most famous commercials to this day: IBM is out of the personal computer business all together, as they sold to Lenovo Group in 2005.
