Nice, but what does
means?
There is really someone who needs a 13" Retina MacBook Air?
The biggest problem I had with removing the Air was that the MacBook has these downsides: high cost; single, not yet widely adopted port; weak processing power. I've since changed my outlook a bit.
I was comparing the rMB mostly to the MBA, as are most of us, but the truest comparison should be to the iPad: fanless device, super compact, typing experience takes some getting used to, etc. Remember that the iPad Pros can be more powerful than the rMB and are becoming more and more enticing with Apple Pencil, multi-tasking, etc.
So, who were/are buying MacBook Airs? Students, older people, really any user on a budget who wants to get on the internet. They don't care about processing power or internals; they trust they get superior quality from any Apple product.
So, for this demographic... why
would you need a laptop? Apple is absolutely correct in that regard. iPads offer more bang for the buck, especially if the users already have iPhones; they're getting another device that runs the iOS that they already know and love. Goodbye learning curve. iPhone SE and 9.7" iPad Pro is a fantastic combo.
The rMB isn't the MBA replacement; the iPad Pro is. The rMB is an iPad with a dedicated keyboard and without a touch-screen. It's for the users who aren't quite yet to go entirely wireless, hence the single USB-C port. The iPad has no ports; so the single USB-C port is an addition, not a subtraction. The rMB also has the potential to drop significantly in price over time, like to iPad Pro levels. So Apple would offer two similar, yet distinct experiences to this demographic.
So, the rMB doesn't need to drop significantly in price for the MBA to be ousted; because the iPad Pros are already here.
I'm also tired of people rehashing the same "I think the rMB will replace the MBA, we're going to have 12"/14" rMB and 14"/16" MBP; they need to simplify the lineup" comment and passing it off as an original, innovative thought. Seriously, we get it. This isn't an original idea anymore and pops up on every Apple community.
