I think the hardest thing would be increased automation, like how some people wouldn’t like being forced to drive an automatic transmission vehicle. It’s quite possible that by then you won’t be able to install your own apps and access the filesystem in OS X - in fact the current version doesn’t let you install your own apps by default, but you can disable this - if it hasn’t already merged with iOS outright. We’re also seeing this in Windows with Libraries. Rather than letting you choose where you want to put things, they’re already suggesting you throw everything in the Library and access it from there. This is pretty much what iOS does with Photos.
The hardest thing will be getting used to the taste of the new, green, high-energy “plankton-based” energy wafers.
Already available. I can see them catching on.
Google Glasses, Microsoft Monocle, and Samsung Spex causing pedestrian accidents on every street.
How about Apple iEye?
The bitter disappointment that Firefly: The Next Generation got cancelled after only 12 minutes on the air.
Hardly unexpected, since the producers were pushing viewers’ attention span past the 10-minute mark.
And that, people, is why a lot of us plan NEVER to really go Apple in a big way.
Not to mention Nokia 'Nads and the Ben Wa Blackberry.

Making ropes from grass, maybe wool if I can learn how to sheer the sheep with the scissors I found in a debris heap a few weeks ago. The evaporative drinking water rig worked out better than I’d hoped–If I make it to next spring I might be able to cultivate some of the surviving raspberry & blueberry bushes I’ve located. It’s still very cold at night, and the wolf coyotes seem ever closer to working out how to get into the chicken pen. The libraries were all burned Before, and I search the wrecked, scorched houses daily for some different kinds of “how to” books. I must also find some glasses, it is so hard to read in the dim light of my shelter. Running out of usable food, I have got to get better at archery. I’m so lonely.
“In the world I see – you’re stalking elk through the damp canyon forests around the ruins of Rockefeller Center. You’ll wear leather clothes that will last you the rest of your life. You’ll climb the wrist-thick kudzu vines that wrap the Sears Tower. And when you look down, you’ll see tiny figures pounding corn, laying strips of venison on the empty car pool lane of some abandoned superhighway.”
You took the words out of my mouth (including the number 12).
Brilliant. And the Sony Sunnies.
Editing photos, word processing, and spreadsheets with a touchscreen after Microsoft dropped support for mouses and keyboards to force people to use the tablet interface with windows 12.
At the right time of day you’ll get decent rates, selling the electricity your car generated to the grid 
People not actually speaking much anymore. Even face to face, they just text each other through their Google Glasses.
Being arrested for destruction of property because I swatted what I thought was a mosquito.
