I started trying to think of situations where a person can have a wrist-worn PC but cannot have a handheld PC with them -- situations where people are constrained for some reason.

The obvious thing most people come up with, is where it's a natural or convenient constraint. You don't want to be holding something extra while you're swimming or swinging an axe or climbling a cliff. I think the related applications are already well-discussed.

What about when it's an artificial constraint? I initially drew a blank on how such a constraint would emerge, until I considered situations where the served parties by the two PCs are different, so that the handheld (if one is present) might serve the user (or manufacturer) but the wrist-worn serves someone else.

Once you start thinking of situations where the user is in an adversarial (or seemingly or potentially adversarial) relationship with the owner then it gets easier to see the applications.

Prisoners, parolees, etc. It's not so much that you let them wear the Pebble or iWatch, as you make them wear it. And your prisoner doesn't need to be surfing the web or otherwise doing things where the PC needs to communicate things to the user, so many of the disadvantages relative to handhelds, become totally irrelevant. The application, of course, is monitoring: being an open spy for the government.

Somewhat similarly: children. Mom wants to know where you are, but isn't really interested in giving you Yet Another porn terminal. Quit fapping and get back to your homework at the libra-- your friend's house?!? Get back to the library!

Marketing. Get 'em cheap enough, and these could replace your "frequent shopper" cards as your cookie. Wear our wrist PC as you walk around our store and check out, for a 2% discount. The application is spying, again. And I guess as long as it has a speaker, it can play location-triggered ads. "Whoa, you just walked right by our delicious canned spoo and instant flarn. Are you sure you don't want some?" The idea here is that you could perform the application with a handheld, but the existing handheld PC would be too pro-user so it might not really play the ads out loud and it might report false travel data. So you want the pro-store computer to be a physically different one. Then it becomes a wrist-worn simply because that's smaller and cheaper ($10 instead of $100).

Sweatshops. The Slurm factory employees are spending too much time on bathroom breaks, and texting their friends. Well, the employee wearable PC doesn't do texts, and it delivers a shock after 90 seconds in the bathroom. If a supervisor ever sees you without your wearable, you're fired.

Jealous spouses. Hubby's "Love Watch" chemical sensors are picking up interesting volatiles: perfume? My, he sure is breathing hard and the GPS has him in a residential neighborhood, not at the mid-town office. Oh, those are just fringe use cases: everyone knows the real purpose of the Love Watch is that it instantly relays every time you speak "I love you" into it. (OMG, that last part is so sickening that I bet a variant of this product already exists today.)

Think in terms of why you might want to "plant" (though not necessarily with subterfuge) your computer on someone else, to be your agent rather than the wearer's. Those may be the best applications for wrist-worn PCs.

Most teenagers I know wouldn't touch old computers.

These days you can easily find Core2Duo and AMD64 class machines in dumpters, and from what I see, nobody wants them. I used to refurbish them for those who wanted and I ended up with a huge pile of decent machines looking for a good home. No takers. I trashed them all.

These ships are as much a part of US history as they are of Canadian.

I guess they have old PC-s.

I have a few machines, all of them run exclusively Linux, all of them can (and have) run Minecraft. Let's see, my desktop replacement is a i7-2630QM with 16GB RAM, my Ultrabook is i5-3357U with 4GB RAM and my desktop is a A8-3850 with 16GB RAM. (I'm excluding my servers here, as they have different use-cases.) Are these machines "old" now? Sure, they aren't brand-new, but I'd say they're all adequate. Surely not enough to run Crysis, but they're no slouches.

OpenBSD truly adheres to "KISS", especially regarding simple configuration files. Exactly of what systemd isn't. It may have (and I'm still not convinced) nice features, but for my uses what is presently being used suffices, both on Linux and especially on OpenBSD.

That was a TV show.

A work of fiction.

You shouldn't take what you saw seriously. It's not real.

What I'm trying to delicately explain to you, is that Heisenberg is still alive.

The difference is that phones are small and you only need to stock a dozen models to serve most clients.

Only a dozen? Let's see... within the iPhone 5S range in the US, we have 3 different storage capacities (16, 32, 64 Gb) in 3 different colour schemes, with 4 different network setups (Sprint, AT&T, Verizon, T-Mobile/unlocked). That's 27. 40 more for the iPhone 5c (5 colours, 2 sizes, 4 networks). The iPhone 4S is still for sale, but "only" 8 options there because it's 8 Gb only now - except the 3 larger ones are still under warranty, so make that another 32. Then we get the 4 and 3GS - but I'll stop there, because we're already at 99 different handsets for the iPhone alone, before we get into Android handsets! Call them $333 each on average, that's $33k of handsets you're mandated to store but not sell. That's insane - just to avoid a 24 hour wait to Fedex a replacement handset to you!? (Not to mention I'd rather have the replacement shipped to me next-day anyway rather than spend hours travelling just to collect it myself.)

Also, I seem to recall some of the Apple fan sites actually monitor stock levels in Apple's own stores - it usually takes a while for stores to have stock on hand after a launch (while customers buy up stock as soon as it arrives), then once a model is old they start running down stocks to avoid being left holding old kit. So, even Apple themselves don't actually carry stock on the scale the poster seems to be demanding, let alone 3rd party repair shops/vendors!

A few years ago, my MacBook Pro's Superdrive failed. Standard part they'd been using for years ... the Store would have a spare in stock surely? No, I had to wait a week for them to get one shipped from Panasonic ... then I was told I'd have to leave the MBP with them for up to another a week to fit it. Of course, by the time I add up the travel costs alone for 3 visits, I'd have spent the price of a brand new external drive, even before factoring in the c 10 hours of my time spent going to and from the Apple Store, so I told them to install the replacement drive somewhere it wouldn't fit easily and bought an external drive.

So, this legislation would be a hugely expensive "solution" to a trivial problem - and, of course, there's no guarantee that on the day your pink 32 Gb iPhone Verizon 5c happens to need replacing, someone else won't already have claimed that one replacement unit, so you can't have it anyway. Would the legislation somehow guarantee a quick replacement of the replacement by Apple, too? Or it would have to mandate everywhere having two of every handset, in case the first one's already taken ...

I'm about two year in (two weeks shy) and my last check (last month) said 8-9 more years at the rate I'm using it. I was told at installation that five is the average. I think the only time I'm paced any more is when I sleep, just due to my natural sleeping rate being lower than the floor they've set. I'll have to ask.

Used the card about a week after I got it due to my place of employment at the time. Haven't used it at an airport.

Damnit, time to change the security question on the password manager for my luggage.

Actually, the number of fatalities isn't countless.

Just gonna leave this here.
