I remember a time, not long ago, when the idea that Samsung and Apple would be in a war for technology dominance seemed laughable. The companies were partners in chip production, Samsung’s products were largely also-rans, and it was perhaps best known for its televisions and home appliances. But now, with the Samsung Galaxy S4’s unveiling almost upon us, we’re here wondering if there will ever be a day when Samsung and Apple aren’t going for each other’s necks. The companies literally can’t stand each other. And although they’re both generating all of the profits in the mobile space, they’d like nothing more than to take each other down.
