According to the latest rumors, the guys from Cupertino are currently working on ARM processors for Macs. Moreover, some insiders claim that Apple has already come up with a bunch of prototypes, including ARM-based MacBook, iMac and Mac mini.

Apart from the new CPUs, some devices are said to be equipped with a brand new keyboard, which can boast of the so-called Magic Trackpad.

As noted by MacRumors,

French site MacBidouille revives rumors that Apple is actively developing ARM processor based Macs. According to a source that they describe as reliable, Apple has prototypes of several ARM-based machines, including an iMac, Mac mini, and 13" Notebook with 4-8 64-bit ARM Quad-core processors.

It would be interesting to see Apple's laptop or desktop working on an ARM processor. You see, these processors are powerful and at the same time energy-efficient. Another advantage is that the switch to such CPUs can possibly make Apple's computers cheaper.
