Is this not the Pro Mac Book version we're talking about?
5 year old laptop may surfice with those demands also. The previous version most certainly would.
Im delighted the new MBP specs and form factor suit 90% of people. I'd be curious to know if the MB or airs would also fit their purposes minus the status symbol and new non essential gizmos.
Probably. Not really the point though.
The 'pro' element really just distinguishes the higher-end laptop range from the lower-end (if you can call a £1k computer 'lower end'). The Air is essentially toast now that the base 13" MBP is there, so really there are just two choices for everyone, consumer AND pro's.... A MacBook with a 12" screen, or a MacBook Pro.
I don't have numbers to back this up, but I imagine the percentage of MBP users that are genuinely using the machine for heavy-duty pro-level app's to be pretty small and many of those people will probably gravitate towards the Mac Pro or a maxed-out iMac just as much as they would a laptop.
But web designers are pro users, as are authors, as are people using the machine for spreadsheets and presentations. None of these people NEED a maxed-out MBP although some may prefer the screen real-estate of the 15". I happily run music production software linked into a workstation (Akai MPC, Turntables, External Monitors, Keyboards etc) on a 2011 non-maxed out iMac. The base model MBP would easily cope with this too, albeit with a few headaches about lack of USB. For ALL these people, as well as the consumers who will use it for more casual use, it's far more about the form factor than the CPU/GPU spec.
I do have some sympathy for genuine power users - those editing film and requiring optimal rendering time, hardcore graphic designers and people using the computer in full music studio's, and for those a maxed-out MBP is a wise choice.
As for 'non essential gizmos', I assume you are referring to the touch-bar. Well, I don't think that is a 'need' in anyone's book at the moment, but it's certainly an attractive 'gizmo' for everyone I would have thought. And has the potential to become a more essential tool in a wide range of app's over time. I could absolutely see why someone may choose a base 13" MBP with touch-bar over a 12" MB or Air right now, even if they are casual users....
