Apple isn't due to show us the new iPhone 5 for another few months, but a purported leak of the next-gen smartphone could well indicate the extent of the headache Android has fast approaching. Taller and thinner, with a more engineered, structured design than the delicate glass and metal sandwich of the current model, if the leaked shots are to be believed then this could be the most significant outward evolution of the iPhone to-date. Nonetheless, there'll undoubtedly be those that look at the slightly larger display and aesthetic tweaks, and dismiss the iPhone 5 as "more of the same." In some ways, the spec-sheet arms race of Android devices has left us spoiled overall. If it hasn't got twice as many cores as before, a vast display, and more megapixels than the latest Canon DSLR, then it's hardly worth us paying attention to, right?
