I'm still annoyed that a device like iPad doesn't support multiple user profiles, logons, etc. Yes, it does support this in a limited way for the education market, but that's not generally usable for others, and it relies a lot on iCloud to refresh one's own data instead of storing/caching as much as possible locally (I'm writing this based on what I remember when Apple introduced this feature a couple of years ago).

But if everything is powered by your watch, then all the external "devices" become essentially dumb monitors. If you could walk up to a monitor and your watch automatically paired with it through Bluetooth and all your stuff popped up ready to be browsed in full HD, desktop sized, wouldn't that be awesome? Of course the watch internals need to be capable of driving full-screen HD, but we're not too far from that.

My watch is more powerful than my smartphone was a few years ago. But my phone is also now more powerful than my desktop was just a few years ago. And my current desktop is just ridiculous.

Of course, my watch is good for mostly telling the time. My phone is good for browsing the web and playing games. And my desktop is good for software development.

I can't help but have the feeling that this was already being said when the iPhone went out and for several years. Yet today, iPhone and iPad are personal devices that is not really shared between users (still no multi user iPad for example). There were some initiatives by Microsoft trying to recreate a desktop experience by plugging your phone to a display and keyboard/mouse but it never really took off.

So IMHO, I don't think this is the future Apple wants to embrace yet even though it appears to be the next logical step in computing for a lot of us.

What about Mac, which supports multiple accounts probably better than Windows ever did (due to Unix underpinnings)?

Windows NT has been multi-user from the start. In fact, due to microsoft's heavy business focus, it's arguable that it even has better multiple account support (a concept separate from multiuser)

Both Mac OS X and Windows NT have pretty weak security protecting local users against each other.

Privilege escalation attacks that require access to the console are usually discounted as unlikely.

This is an unsubstantiated claim.

Certainly, there have been a fair amount, but not for lack of effort on the OS developers' parts.

It can always be better, and cutting edge, modern OS designs are superior, but it's not like the foundations of NT/Darwin are completely rotten.

Um, what?

Lolz, no it doesn't. The securetoken stuff means that directory service stuff is broken without doing stuff like storing plaintext passwords on the device. Windows has had much better multi user support for years.

Apple seems to fundamentally believe that Macs are single user systems, and it's shown in their past few major releases.

That is annoying. I really believe in a future tech world where you just use whatever device is near you (wall screen, screen on a table in a restaurant, devices in friends' and family's homes, etc. It gets old carrying around devices and chargers.

Maybe Apple won't be the vendor for this.

Every family I know has a "family iPad".
