> But why bother putting a real driver in here at all? Magnets not only add weight, they take up a lot of space. Looks like one corner Apple refused to cut on this tiny disk is sound quality. I find it fascinating what tradeoffs are decided upon. Apple is arguably the best luxury brand in the world - and this is why.

It will also make them better hidden microphones :) http://in.bgu.ac.il/en/Pages/news/eaves_dropping.aspx

The lack of loophole was disorienting, but then I went and looked up how they want you to attach it, and the hangtag accessories look so pretty https://www.apple.com/newsroom/2021/04/apple-introduces-airt... -- things like the appearance and the sound quality really show a commitment to making polished products rather than practical ones. I've been fairly negative on Apple for a few years and they still need to pull…

Sheesh, those are costly. $35 usd is more than two weeks worth of groceries, two months of a world of Warcraft subscription, and about the same price as any of Affinity's products. For the AirTag, I'd admit that it seems sophisticated enough to warrant it. But the loop to affix it!?

Keeping your food budget at $2.50 a day is impressive. Do you do a lot of bulk food prep?

I used to get by on $3-3.50 a day, but that was back in my lean years.

> It's hilarious to a certain extent that they built the thing smaller than all the competition and bulk it up with a wad of leather anyhow. That's essentially how I feel when I see the "Our thinnest iPhone ever" slide knowing that 95% of iPhone owners put it in a bulky case. That said, that's not unique to Apple and the phone is at least usable without a case.

I know it means nothing but I'm in the 5%. I've never had a case on my iPhone and I've owned every other generation since the original (I always skip generations for my devices since they started doing the incremental S versions). I prefer things without cases and the AirTags are going to be no exception. I'm going to throw them into a pocket or put them into an already existing spot so I like that it's thin.

What are you going to track without using some kind of holder?

Personally, I only bought one AirTag (along with an Apple leather keychain, for my keys). I don't generally lose items large enough to have some kind of pocket/holder for an AirTag (e.g. I don't ever lose my backpack which has a zippered compartment to hold random junk).

* for computers. From what I've heard, their chipsets don't have the same problems as the ones they use in macs.

The M1 Macs are essentially iPhone/iPad hardware. The latest iPad Pro shares the same M1 chip, and I imagine it shares most other components as well.

Right, but the wifi+bt chip is still Broadcom.

What exactly is 'UWB functionality'? Are they using UWB for RF localization? I assume you would need multiple beacons for that? Are they using the phone as a single beacon? Wouldn't this just give you a radius rather than a location?

With just one phone your phone can point an arrow in the direction of the airtag and give you a distance to it. Tested it out a bit and it works pretty well but its short range.

It's not like the choice is "thick and doesn't need a case or thin and needs a case". Even if the phone was thicker, people would be using cases if they bought it, right?

> Even if the phone was thicker, people would be using cases if they bought it, right? People started using cases for most part after the iPhone came out. Older phones were almost never used with a case, except perhaps for use case requiring a ruggedized enclosure.

BlackBerry phones had those holster cases, and I remember my dad's first cell phone (a Nokia, around year 2000) had this fabric and clear plastic case that the antenna pokes out of (like the sibling comment describes). Even though that phone was indestructible, with big rubber buttons and a plastic screen.

I mean, you can also buy a holder from Hermes for $350.

The belkin one is only $13, and I'm sure there will be some from China on Amazon for $2-5 before long.

Back when phones were built to survive the outside world without a case, I never put cases on my phones. The whole Nextel and Nokia and Blackberry era, not a one. They looked a bit worn from a few years each in my pocket with my keys, but they all worked fine, and they'd all survive a drop to the floor. Today the only phone I'd trust to survive a naked drop would be a Unihertz Titan, but until there's an AOSP ROM for…

Back when phones were built to survive the outside world without a case You mean: Back when phones had screens made of plastic instead of glass. And yes, sure, that does make them more likely to survive a drop, but also means the screen becomes a scratch magnet. That of course is the right compromise when the screen is tiny and the pixels are enormous, but not so much when it’s the other way around.

Until about 2013, I didn't use a case on any of my (Android) smart phones, and never broke the glass screen. I know I dropped them several times. The worst that would happen was the battery door would fly off. I started using a case when I got a phone that was thinner, and had a glued-in battery. I think having a removable battery actually makes phones tougher in a sense, because I the case of a drop there's an place for the force of impact to go without causing permanent damage.

Yeah maybe. But from what I've heard the product can do, it'll guide you with a heading pointing towards where the product is. It may be that the iPhone has some sort of dual antenna functionality where the difference in time between signals being recieved can be used to find the direction.

My initial intuition was that uwb localization was still in research paper territory.

The only previous commercial example I can think of is those Razer Hydra gaming controllers.

Pretty interesting that is come around to a mass consumer product with Apple.

Rumor has it that this might be changing soon.
