Is Apple ok? There have been quite a few (unannounced) projects delayed or cancelled recently and lots of high level staff leaving. Seems like a lot is changing behind the scenes.
In this case I'm totally fine with it because this is not something Apple really needs to do themselves. I'm not sure it would even be a nice-to-have beyond the cost savings. As mentioned in the article, now is not the time to muck about with rolling your own wireless. Let the specialists do it and just buy their specialized products.
Now when it comes to cutting corners, that's where I'm starting to have concerns about Apple. But I'm glad they're not pushing ahead with in-house chips that they know aren't ready solely for the cost savings.
