Una entrada en Cult of Mac que me recuerda a ese rumor que un desarrollador alguna vez me ha dicho que ve venir ya hace tiempo: una nueva transición de procesadores en nuestros ordenadores favoritos.

«… Apple has been quite promiscuous with CPU architectures in the past. We’ve already witnessed two major transitions for the Mac. First from 68k to PowerPC. Then from PowerPC to Intel. That these transitions were so seamless is arguably one of Apple’s greatest technical achievements to date. While developers may have grumbled about having to port their apps to the new architecture, for the most part they did rather well out of it, since it gave the likes of Adobe a great rational for charging their customers hefty upgrade fees.

Of course, Photoshop, Final Cut Pro and Logic users are hardly going to be switching to ARM-based Macs any time soon. ARM is just not powerful enough for pro applications. But for most of us, the advantages in price, size and battery life would certainly make them an attractive option. ARM-based Macs also present the intriguing possibility of dual-mode devices, that could switch between touch-screen and point-and-click input modes. For example, an iMac that unplugs to become a giant tablet, or a MacBook Air that flips over to become an iPad. Both Mac and iOS apps could run on such a device without needing to be ported.

When some commentators predict that Mac OS X and iOS will merge, they describe a hybrid user interface, based upon touch, but with Mac point-and-click features as well. To me, this seems unlikely. If Apple had believed that the Mac UI could be adapted for tablets, wouldn’t they have based the iPad on it, rather than iOS in the first place? But dual-mode devices that can switch between touch-screen and point-and-click modes, supporting both iOS and Mac software certainly present interesting possibilities. And cheaper, smaller Macs based upon A4 chips have the potential to make the Mac platform more popular than ever.»
