The PC’s greatest secret weapon is hiding in plain sight, right under the sticker that says “Intel” or “AMD” inside. Even a budget notebook has more raw processing power available than a high-end phone.
However, few apps take advantage of all that extra performance. Where Windows Vista pushed the hardware envelope with an Aero interface that required faster components than many users had, Windows 8 and all of its apps shoot for the lowest common denominator.
PC OEMs need to work with Microsoft and other software publishers to build more must-have apps that require or at least take advantage of newer processors. As it stands, most users don’t see a reason to upgrade from a first-gen Core i3 to a third-gen Core i7.
