Barence writes "When Steve Jobs announced last night that he was 'going to demote the PC and the Mac to just be a device,' it was the clearest indication yet that Apple is phasing out Mac OS X, argues PC Pro's Barry Collins. 'Over the past couple of months, there have been continual rumours that Apple is testing the iPad's A5 processor in its MacBook range, suggesting Apple believes iOS could stretch further than smartphones and tablets,' Collins argues. Plus, Apple would take a 30% cut on all Mac software if it mandated downloads via the App Store only. 'The only part of Apple's portfolio where iOS doesn't make sense is in the high-end. Yet, Apple's already discontinued its Xserve range of servers and... it's almost exclusively fixated on the consumer market,' he argues."
