There are a few things I have witnessed becoming obsolete in the past few years, the first being autographs. I haven’t been asked for an autograph since the invention of the iPhone with a front-facing camera. The only memento ‘kids these days’ want is a selfie. It’s part of the new currency, which seems to be ‘how many followers you have on Instagram.’
I’d say it’s probably 70/30 on iDevices vs. MacBook. Most of the MacBook Air time is work-related. And that figure is so heavily tilted in the iDevices favor because I use the iPhone far more than any other device.
That said, when it comes to “general computing”, I much prefer to use the iPad Air (with the Logitech keyboard) for almost everything. But I suspect a rumored 12” Retina MacBook Air could tilt the numbers back in the MacBook favor, if only temporarily.
We don’t take so long and make the way we make for fiscal reasons. Quite the reverse. The body is made from a single piece of machined aluminium. The whole thing is polished first to a mirror finish and then is very finely textured, except for the Apple logo. The chamfers are cut with diamond-tipped cutters. The cutters don’t usually last very long, so we had to figure out a way of mass-manufacturing long-lasting ones. The camera cover is sapphire crystal. Look at the details around the sim-card slot. It’s extraordinary!
Yeah, I’d imagine (though have no actual knowledge) that we’ll see a 128GB iPhone in the next iteration. Maybe that means the end of the 16GB model, or maybe it means that’s reserved for the more affordable version.
The one thing working in the other direction is the movement of all entertainment to the cloud. That is, Spotify, Beats, Rdio, iTunes in the Cloud, etc, allow you to keep a lot less music stored on your device these days (though some is saved for offline capabilities, of course).
Still, while that has alleviated some of the need for a lot of storage, apps continue to grow in size — particularly games. Many are over 1GB now. 16GB seems untenable. And 128GB seems inevitable. (And that should drive the price down of the 64GB models, etc.)
Update: As, of course, as my buddy Cap notes, photos and videos are driving this need for more storage perhaps above all else.
