I should clarify my previous statements a wee bit:
I agree that the Mac is not going away anytime soon given the iPhone. On the contrary the iPhone MultiTouch/OS X thin client experience makes Mac OS X all the more central to a Mac user's experience and OS functionality.
Yes - you're right - we'll continue to use our Macs for intensive, finely-detailed tasks. But I DO think that Mac OS X WILL steadily absorb and incorporate the winning elements of iPhone OS X thin client.
MultiTouch, for example = simpler more intuitive app UIs that takes full advantage of touch screen interface, instant voice/video-based IP messaging and much easier, more direct way to get tasks completed by leveraging the exponentially-growing power of the CPU, the internetwork and its distributed and diversified resources.
So - let's imagine a possible scenario - you're leaving on a vacation with your family. You don't want to bring your desktop Mac with you but do want to have 24/7 access to your Mac while you're away. So what do you do?
You take along your iPhone, or your iWhatever - a portable device that runs OS X thin client with a MultiTouch screen and UI.
You bring along the files you think you might need, storing them locally on your iMobile device.
I'm not saying the original iPhone v1 will be able to do the types of tasks I'm going to describe, but by v3 or so it will! As on-board CPU, memory, file storage, battery power management, network access, etc. scale-up so will iPhone's functionality expand in kind.
Plan to see more and more of Mac OS X's apps and functionality turning up in one form or another in iPhone and, vice versa, more and more of iPhone's UI turning up in Mac OS X. They will form an integrated and expanding Client/Server/Client relationship that will join them at the hip by enhancing each OS's ability to access the other OS' powerful features and advantages.
So - back to our vacation - you are checking your email, your voice/video messages and viewing attached files, etc. and, Murphy's Law, a fire starts that you hadn't planned for during your vacation. You have to act - now, fast and smartly - to put the fire out so you enjoy your vacation with your family and still have a job to come back to!
Out comes your iPhone. You video iChat with three of your co-workers and determine what to do, delegate the actions and schedule another iChat the next day to follow-up and confirm conflict resolution. Next, you upload the files your co-workers will need to your secure .Mac work folder and email them the access info.
You need to edit some of those files before uploading them so you remotely boot and access your work-based Mac's OS X screen, open the files, make changes, save them and directly FTP them from your work Mac to your .mac work folder and let your co-workers know they're available.
Whew - now you're free to return to your vacation with your family. The next day you log-in to the scheduled video iChat with your co-workers. They got the files, used them for the actions required, and the fire's put out - quickly, professionally and with precise expertise.
OK, OK, I may be way off in my estimation of what's actually possible using the iPhone, iPod, iUltraportable, iWhatever over the next few years. But this is where Apple and this new UI is headed. It will be directly and powerfully linked to the home-, work-based, wired Macs running Mac OS X via services running on OS X Server and other web-based services.
Apple mobile devices will exploit and leverage these web-based services, processes and applications like never before! They will feed off each other for innovation and functionality! iPhone will drive back-end services development and back-end services will drive iPhone app development.
And Mac OS X, the thick client in the middle of this thin client/server interplay will also benefit. It's a synergistic, win-win-win all around and the ultimate winner is the consumer who gets easier to use, more and more powerful and smarter and smarter functionality from their Apple universe = iPhone, Mac OS X, Mac OS X Server, Mobile Carrier Network and 3rd party network servies, etc.
iPhone and its progeny WILL strengthen Mac OS X and Mac OS X Server and all subsequent products and services that develop due to iPhone's success.
Chris - I have to respectfully disagree with your overall summation of iPhone and Mac future market potentials.
And, for the most part, I agree with all the highly-intelligent and well-articulated comments on your article (that's an indirect kudo to applematters.com for attracting such a great and involved readership and I include myself in that demographic).
OK - my 2 cents worth - to add to the comments made about the 'digital hub' concept that Apple has been steadily and successfully building-out alongside OS X - the iPhone IS a new UI, an entirely new user experience: a robust, scalable, mobile OS X THIN CLIENT (for the sake of brevity let's dub it XTC).
XTC is the key that unlocks a dynamic new future for OS X, Mac and all of Apple's inter-related products. It's the next logical extension to their 'digital hub' model and it's a helluva quatum leap.
As XTC matures (2 yrs = v3) we'll see more and more Apple AND 3rd party apps running as thin XTC clients accessing powerful and distribulted OSX Server apps AND apps running locally on your Mac or PC (doable using current avail tech). I include 3rd parties in this statement as they've always been invaluable and integral to Apple product and solution development. Apple Developers' input is inevitable and fundamental to XTC's market success and will appear once Apple sorts out sensitive security and malware/cracker issues on mobile networks, etc. It's just a matter of time.
It's not hard to imagine logging into your LAN Mac/PC/Server/SAN from XTC iPhone/iPod/iUltraportable and remotely working on local apps like Office, FileMaker, iLife, iWork and saving/moving/forwarding/backing-up these files in real-time, even streaming your iTunes media content directly over IP to XTC. And XTC is leveraging the processing/routing/streaming power of the LAN at every step - Server/Mac/PC/SAN! I could go on but you get the idea.
In short, iPhone is an entirely-disruptive, preemptive r/evolution to the mobile/ultraportable marketplace. MultiTouch UI aside (which is the unique and intuitive user experience which drives this whole equation) XTC is the potent, mobile, thin client portal to universally-distributed and infinitely-diverse, web-based services.
Factor in GPS, WiMax, 3G, .Mac, Skype, VOIP, iChat AV, YouTube, Google and on and on, and you've got a kick-ass killer called 'anyapp/anyservice/anywhere/anytime/andhow'!
XTC finally and fully realizes the rising Sun IP prophecy: THE NETWORK IS THE COMPUTER! And the 'internetwork' just got a major Apple upgrade!
