Apple's business is not one that has to own a market to make gobsmacking amounts of money. As such I doubt they see being outsold by Chromebooks as being a serious problem; they've been being outsold in the laptop market forever and are still making yachtloads of cash.
And as to sustainable business models - the iTunes Ecosystem alone is a large as half of Google's entire business and is growing faster.
Most Chromebooks are glorified phone hardware. Even the one with the whizzbang screen has lousy soldered-on local storage, so it fails as a microcomputer. It essentially is a terminal with a fantastic screen. I certainly wouldn't attempt to use one to develop on (and I mean develop on, not RDP/VNC/SSH to a box elsewhere). Could I write C++ on it for multiple OSes thanks to virtualization on a Chromebook? I know my needs are niche but I don't think Chromebooks compete with MacBooks, even if they look similar-ish and one has outsold the other. Out of interest, have Kindles outsold MacBooks? Would that be the death-knell for MacBooks? Really is comparing Apples and Oranges I think.
Do you supplement the internal storage with external? Is it a hassle? My Windows VMs are all 50GB+ so having tiny internal SSD storage is crippling.
Except, you know, IBM doesn't have anything to do with Thinkpad anymore, and hasn't for years.
Thinkpads are now Lenovo, not IBM. And MacBooks do run official Unix, so it'd make sense. Plus, he can look cool in a coffee shop :-)
(I love my MacBook, but don't use it coffee shops, as an aside.) Your point about iPads is very true. My wife has an iPad and it is joy to use. I have a Motorola Xoom that I really do love using and find very very useful but the standards aren't the same. I know the Xoom is old (some would say ancient) and is easy to develop for but the iPad truly does rule the Tablet waves.
And the iPad, which is kicking the hell out of Android tablets (to my consternation, because I'm primarily an Android user and their tablets are terrible).
And the Macbook Pro, which is making pretty major inroads at leading-edge companies. A buddy of mine is working on *nix software at IBM and they asked if he wanted a Thinkpad or an MBP; that blew my mind.
They don't do big iron, but they move a lot of product and very little of it is faddish. They Get It, or have Gotten It historically, and a lot of people respond well to that. They might at some point no longer Get It, but until then, saying that they only have the iPhone going for them is wishcasting.
