    Wide spread, end to end encryption would need to be implemented.

    Nice in theory. Not so much in practice. With crypto, the devil's in the details. Here are just a few of the hard problems:

    • Initial key exchange: How do you know whether that public key really belongs to the person you want to talk to? Physical exchange of a key? Key signature? Web of trust? Or just trust a service provider and hope for the best?
    • Key updates: Periodically, you'll need to upgrade to a longer key and a new cert. How do things work during that interim period?
    • Expired certs: At some point, those keys are going to be crackable. How long do you trust the expired certs for messages that have already been received?
    • Key revocation: How do handle it in a way that ensures that it can't be readily blocked without also blocking the main data channel?
    • Key revocation: How do you handle the inevitable situation where someone's device dies and they don't have a copy of the original key at all?
    • Key storage: What sort of protection is in place to minimize the risk of the key leaking?
    • New devices: How do you migrate the key to new devices securely?
    • Ability to audit: How do you know that things really are being encrypted end-to-end? What about after the software gets updated?

    If it were easy to do it properly, end-to-end crypto would be ubiquitous.

    Designing an API properly does take a long time, but they had to do that anyway for first-party apps, whether they made it public or not. To be fair, the bar is a little higher for a public API because of the need for maintainability, but it isn't that much higher, particularly given that the non-UI parts of the SDK were mostly shared with OS X, which was already a public API.

    That is indeed what he said, but I suspect that was just spin.

    I'm about 99% sure it wasn't. As evidence, I cite the fact that the head of the iPod team left Apple for Palm and started an OS that was web-based just like iOS was originally going to be. I think it was more that the people Rubinstein left behind clung on to the iPod mentality of a closed architecture that allowed only a handful of developers to write code for it for a very long time before finally giving up.

    I think the iPhone was successful before they supported 3rd party apps.

    Not particularly. The pre-app-store iOS market coincides precisely with the original iPhone's sales. Apple sold only 6.1 million of them over the course of about a year. The iPhone 3G sold a million in the first three days. And yes, the original iPhone hardware was behind the times, so that contributed to the difference somewhat, but there's little doubt that the App Store is a big part of why iOS is a success.

    Want to know how I know this? Palm WebOS. Notice where Palm's top engineering management came from. Yup, you guessed it. Apple. They followed Apple's original plan, and they completely cornered the market... no, wait, that other thing... tanked.

    Chromebooks have the advantage of four more years of improvements in web browser technology. With that said, remember that the #1 thing people do with their phones is play games, and that games are pretty high on the list for laptops as well. Without native apps, gaming isn't very practical, which is why the Chromebook is still just a low single-digit percentage of laptop sales, and why a web-only phone would be pretty much DOA even in today's market, with today's technology.

    It wasn't Apple that killed Nokia; it was Android. Their big niche was cheap feature phones. When Android came along, suddenly, there were cheap smartphones, and nobody wanted cheap feature phones when they could get cheap smartphones. To be fair, Apple had a lot to do with forcing the UI changes in Android that made it popular, but the mere existence of Android in any form would have pretty much cut the legs out from under Nokia.

    As for Blackberry, Apple didn't really start killing them until much later, as iPhone hardware wasn't really all that welcome in the business world until after Apple started adding stuff like mobile device management. I always found it odd that they were a hardware manufacturer, given that their hardware was fairly boring, and most of their interesting creations involved software and services. I'd expect them to reinvent themselves as a software and services company fairly handily, and freed from the shackles of having to build their own hardware, I'd expect them to do fairly well.

    Ericsson got bought out by Sony, who still builds plenty of phones and other devices. Given Sony's size, I wouldn't count them out just yet. But if somebody does drive them out of the market, it will be Samsung, by undercutting them.

    Yeah, but park ramps have been around for a couple of decades (the earliest patent filing I could find was filed in 1992), and they only started having insane levels of trouble fairly recently (by comparison). So it's probably the combination of excessive amounts of parking (as you mentioned) and having less structural support for the heads that makes them so problematic.

    Not all devices show LTE bars identically, so your mileage may vary. To compare apples to apples, we'd both need to be using dBm. Truthfully, even that wouldn't necessarily be a valid comparison, depending on multipath interference and a whole host of other factors. My point was that there are a lot of places that have service, but where the minute-long connection latency caused by high packet loss results in such a horrid real-world speed that it might as well be truly slow.

    Would be nice. I also wish they'd go back to the pre-retina enclosure, and instead of wasting space on an optical drive, I'd like to see them use most of that extra space for additional battery capacity. If I run Photoshop or Finale or Xcode or any of the other software that I use to actually get stuff done with my retina MBP (about one year old), I'm lucky to get 2.5 to 3.5 hours out of it. If I were designing a computer to meet my needs, the "four cores running at full tilt" duration would be eight or ten hours, and the "just wasting time doing light-duty web browsing" number would be measured in days.

    Or just bring back removable batteries. Either way.

    Union contributions are, more or less, under the control of the people who are in the unions, and if you don't agree with a union's political agenda, you have a legal right to withhold that portion of your dues, so your portion of that contribution is 100% under your control.

    Corporate contributions, by contrast, are entirely under the control of its board of directors. As a shareholder or normal employee of that corporation, you have no control over your portion of the contribution. Corporate contributions represent a concentration of power in the hands of a few individuals, which makes them fundamentally different.

    Real-world LTE speeds only qualify as broadband if you're very close to the tower. By the time you get into two-bar territory (where their LTE network is "available"), you'll be lucky to get EDGE speeds, and at one bar, you'll be lucky to get any data at all. Yet technically, LTE is available in all those places. That's the problem with wireless; the speed falls off a cliff as distance increases.

    In a curiously ironic twist, the hardware designed to protect consumer-grade disks from damage ends up destroying them. As I understand it, a number of fairly recent consumer drives exhibit a higher than normal failure rate because the heads break off of the arms when they collide with the park ramp. This is, at least in part, a consequence of making the arms smaller and lighter to improve seek times.

    At more than 8 cents per gigabyte, archival DVDs are horribly expensive. You could cycle your backups across three hard drives for about the same amount of money, and then you have three backups instead of one.

    Hard drives are really the only viable backup medium unless you have a big enough collection of data for tape drives to make sense—maybe Blu-Ray, but only if you don't have more than about a 100-disc spindle worth of data (2.5 or 5 TB) to back up (and really, most people lose interest at more like ten or fifteen discs).

    I think the point was that after you clone your backup drive to a new one, you can reuse the drive to replace or expand your main system drive, whereas once you burn an optical disc, "reburning" means throwing away the old plastic (or keeping an extra copy around). This effectively makes optical media a lot more expensive than magnetic media.

    But do realize, that was an outlier and is atypical of what Apple does.

    No, it isn't atypical, at least for early-generation Apple products. The average support period for Apple is about three years, and there are a fair number of products that got less than that (mostly early models). For example, here's the time between the release date and last supported update of some other first-generation and second-generation Apple iOS devices:

    • Original Apple TV: 3 years, 1 month, and 1 day
    • Original iPhone: 2 years, 7 months, and 4 days
    • iPhone 3G: two years, four months, 11 days

    The support period tends to vary based in part on how many of the devices are out there in active use, and in part on how badly underpowered the hardware was to begin with. So later products in a given line are likely to have longer support periods than earlier products.

    Actually, the telcos in Europa are preparing to roll out G.fast, which makes telcos again competive with Cable.

    Not really. We hit the bandwidth limits of a single twisted pair a long time ago. For G.fast to be usable, the phone company has to replace your phone line with fiber to within just a few hundred feet of your home. For it to reach maximum speeds, you need fiber within just 230 feet. In effect, this means that if the phone company replaces all of their copper with fiber, G.fast lets them skip the cost of running the fiber from the pole outside your house into your house, for now. That's about it.

    If your community has no fiber, G.fast won't even connect unless you're within BB gun range of your central office or DSL-capable remote terminal.
