I have no inside information or insight, but historically Apple’s product improvements have strongly broadcasted where they’re going in the future. Here are six things I think are inevitable for Apple to do over the next decade, from most to least obvious: maps, iCloud, payments, TVs, search, and cars.

1. Maps

When the iPhone was first released Steve Jobs called Maps on iPhone the best version of Google Maps on the planet, with emphasis on what Apple’s designers had brought to Google’s raw technology (can’t find that link). Four years later, you can’t imagine such a core piece of the mobile experience reliant on their largest competitor. Hopefully this will also give Apple a chance to fill usability gaps in the maps experience today, like that you can’t click from the “where” field in a calendar appointment straight to maps. (Drives me crazy.) Note that the only “Google” branding in maps today is in the bottom left, they know they’re getting replaced and have done an admirable job on the Safari version of maps on iPhone and iPad.

Google Maps + Navigation on Android is my favorite mobile app of the past 3 years (haven’t used Siri yet) — it’s what Garmin should have built $8 billion in revenue and R&D ago. (Remember the Garmin Nüvifone?) Apple was smart to partner in the beginning, but they can, and should, raise the bar.

2. iCloud

The abstraction of documents, photos, videos, their equivalents in “bought” media (iBooks, music, movies, and TV shows from the iTunes store), the deemphasis of the filesystem with every iteration of OS X, and the rough ideas of things like MobileMe’s dock syncing, points to the combination of services that will ultimately disrupt the “magic folder” providers like Dropbox. I love Dropbox, but it’ll be impossible for them to do the deep OS integration needed to match the direction Apple is heading — never thinking about what is where, ever again, just having everything you’ve ever created or used available in the same place on all your devices.

They know this is best for consumers. My friend Rene told me how when his hard drive crashed last year he contacted Apple support and they gave him a link to re-download the past 4 years of music he’d purchased on iTunes. That’s obviously the right thing to do, even if labels have had to be dragged kicking and screaming toward it. By this time tomorrow it’ll just be part of the experience when he signs into iTunes on a new computer. Update: Apple released iTunes 10.5 a day early with this feature.

3. Payments

Your phone becomes your credit card. Apple doesn’t replace Visa or Mastercard, but they do replace all of those scammy rewards and branded cards that prey on unsophisticated consumers. Google will probably do this first, but it’ll be like Microsoft Surface, brilliant but two sandwiches short of a picnic.

4. TVs

I recently got one of the new Thunderbolt displays and man, a super-sized version of this would be killer in my living room. (The speakers are surprisingly good.) TVs are just so bad, not so much in the hardware which can be beautiful like Samsung’s C9000 but in the mediocre software, un-features like Auto Motion (which makes beautiful films look like they were shot by a Jersey Shore cameraman with a beer in his other hand), and interfaces that just don’t do anything you would expect. Hello — you can detect when a cable is plugged in, don’t make me switch between 15 sources when only one is connected. My TV takes 5-10 seconds longer to turn on than my iPad. “Smart TVs” look like “smart phones” did in 2005 — completely lacking in imagination or joy.

But to really imagine the strategic importance of this you need to think beyond a super-sized Thunderbolt display and imagine what replaces iMac, one of Apple’s most beautiful creations. People’s need for a desktop is seriously declining for the first time since pundits started predicted the decline of the PC a decade ago. The post-PC ecosystem is in place now — touch, battery life, mobile-first applications, ubiquity of internet access, flash memory. (In Steve Jobs introduction of the first iPod, two things stand out to me: that terrible font, and the fact one of the main features is 20 minutes of skip protection.) Mobile works and is getting better, and you won’t have what we call a desktop 10 years from now.

Now imagine Apple has a shining 55″ monolith smack dab in the middle of your house. How big of a wifi antenna could they put in there? Could they crush all that lame Cisco teleconference stuff with TV FaceTime? Is there room for a few disk drives that don’t need to worry about skipping plus a SSD to make it fast? If you look at the direction Apple has been heading with Time Capsule locally caching software updates it’s not hard for something similar to work in the other direction, a digital hub that’s your media server for the house, a large-format display, a time capsule, and an Airplay target all in one. Imagine just one power cable coming out of it, and everything else wireless, just like the iMac, and a few killer apps we can’t even imagine yet.

Finally, home theatre needs disruption — this is a land of $200 Monster HDMI cables and similar gouging that functions like a state lottery, an intelligence tax. When I walk through Best Buy, which I try to do once every few months, it feels like it’s technology at its worst, the magic of progress used as smoke and mirrors to confuse and dupe consumers rather than make their lives better. The Apple TV is just another form factor for the unified experience Apple wants to create every time you touch an electronic device.

5. Search

There are hints of this in maps, but just like Craigslist is being killed not by a Craigslist-like clone but rather by a thousand highly focused replacements, so too Google will face its existential crisis not from another webpage with a centered white box, but from the interface and context of search changing completely. Many of Google’s searches aren’t that valuable, and a huge percentage of the ones that are aren’t going to happen at the desktop anymore .The context of your location (which your phone already knows) the “results page” of a fantastic map application and the input of a next-generation search interface, like Siri, completely changes the rules of engagement. Google’s not investing in mobile because they wanted a better phone.

6. Cars

This is the most far-out, but I think most certain. Voice-controlled search through Siri and Apple Maps provide the hands-free framework for a rich interactive experience while driving. Walk down the car stereo aisle in Best Buy and see what $800 gets you, or a $300 GPS from Garmin, vs an iPad or iPhone. The screens feel like a TI-92 calculator. The typography makes my eyes bleed. I find it morally reprehensible how bad these products are because it’s one of the areas of technology where a bad interface is most directly tied to injuries and deaths. Car folks are making their iPhone/iPod integrations better and better, which may be a glass of ice water in hell, but they’ll never make the jump to providing a beautiful marriage of media, search, and navigation that a great in-car experience needs. Right now you can spend 110k on a Tesla Roadster, a car of the future, and for an additional $4,500 (9 iPads!) get this Alpine head unit. (Watch that video and try not to laugh at how bad the interface is.) Retail it only sets you back 1.4 iPads. That’s just sad.
