Apple’s MacBook line has changed significantly in the past few years: screens have been upgraded to Retina resolutions, optical drives have disappeared, and upgradability has been curtailed to reduce size and weight. But there’s one notable exception: the 2012 13-inch MacBook Pro, which remains surprisingly popular. Developer Marco Arment lists some reasons why he thinks that’s the case, including the machine’s optical drive, upgradable RAM and hard disks, and low cost. Apple should be asking itself if the constant push for smaller and lighter is meeting the needs and desires of all of today’s users — keeping old models available isn’t a long-term solution. We’d like to see Apple serve this group of users with a new MacBook that retains the design goals of the 2012 13-inch MacBook Pro while using newer technologies. It’s not like the MacBook line could get any more confusing than it already is.
