Apple truly is doing an amazing job (along with ARM, etc..) in making the A series of processors an amazing chip & platform, and I'm proud as an Apple device user to have them in my mobile devices like the iPhone and iPad.
With that said, I hope that Apple doesn't start putting them into their Mac line of Desktops & Laptops, not Even the Air.
The iPad Pro, and similar iPads serves the market where the A chip can shine. But if they put it in an an actual laptop called a "Mac" I am concerned that it would cause market fragmentation and confusion. Most people I know using Macbook's (Pro/Air/etc) also use VMWare Fusion or Parallels, or BootCamp, etc... and even people that don't will I think get confused why their Steam Games or GOG games, or other applications are no longer supported or no longer perform as well. Intel isn't shining like it was when it brought out the Core Duos, the i'series, etc. but They are still great chips, and if Apple would update to having current gen CPU's and chipsets then that would have more benefit I think.
As a fan, a shareholder, a (novice) developer, an Apple user since the Apple IIe, and any other categories I could be classified into, I do not want to return to a similar scenario we had with PowerPC's they also we good chips in their own right, but moving to Intel X86/X86_64 was a breath of fresh air that I hope we don't forget about.
