I would fully expect Apple to retain and update the MacBook Air.
To reduce cost, Apple can use the cheaper Kaby Lake Y-series processors. These processors are not only less expensive, but they also use less power. This means smaller batteries. The MagSafe port and card reader are gone for sure.
It's important to understand why the "Air" was dropped from iPad Air. Consumers were unwilling to pay $499 for a media consumption device and we saw that with tanking iPad sales. Nobody was buying the iPad Air 2. In fact, it's not even available on the Education Price List.
Due to price, the MacBook Air remains a popular choice for many, especially in education. In fact, the 11-inch Air is still available to order for $749. Clearly, there's demand for this old, but cheap notebook. So it makes sense for Apple to launch a $799 or $899 refreshed Air.
Really agree. People love their MBAs.
I’d expect just one more update to this line.
Apple needs a reasonably cheap modern laptop (students, journos... anyone...!)
I expect that we’ll see the body of the MBA refined & made a little thinner, but still keeping its wedge profile.
[And the processor updated to the KL Y series added as you say.]
EDIT: I don’t really know my intel processors and they have so many, it’s confusing! Actually my best guess is they’ll use the 8th gen U series for the new Air.
Oh yeah and an updated keyboard design.
A Retina display of course. Likely the same one from the MacBook. Good but not great.
And the trackpad from the MBP. Probably not with force touch (who uses this?).
I’d be really surprised if we see MagSafe and USB 2.0 retained though. Ditto the other ports. I think that we’ll see x2 USB 3.x ports [EDIT: oops I meant USB-C]
Since the original iMac, this is what Apple does - it’s always been ruthless about removing what it sees as outdated ports.
So what I’m describing is essentially an entry level MBP (minus TB) & this is what the AIR will replace, but likely doing what it can with using cheaper mid-range components wherever possible.
I wouldn’t be surprised if we see the MacBook retired for the moment, in readiness for a relaunch with ARM chips.
The Y series chip that powers this model is still very very expensive for its performance.
And I think that a new AIR will help Apple differentiate further the MBP range which I expect will lose its cheap entry level 13 inch model - because that’s what the new Air will be.
