There's also a cached version of an old magsafe article on that website by the same author at https://webcache.googleusercontent.com/search?q=cache:msNKQI...
Feels like a requirement to do wireless charging (note, I have not played with wireless charging despite having it on and off since 2010, so I could be mistaken).
A Magsafe cable/port is a "trip safe" charging system, as the power cable is attached to the computer solely by magnets so that it will not break the port if yanked out at an angle.
Which at least 10 years ago used to be a big issue. Not sure how current iterations perform.
However, the magsafe feature on iPhones is something completely different, it's the system where they have magnets in the back of the phone which can be used to attach various accessories, attach the phone to mounts, or guide the phone to rest correctly on wireless charging pads.
That was around 2010, as well.
I'm not a fan of cases, so it hinges on how bulky it is. But it looks like a solid product.
My understanding is that Qi2 will be magsafe-compatible, which bodes well for future android phones and accessory support.
UK printed train tickets are all magstripe. There are phone-based alternatives and contactless payment card alternatives in London. But the magstripe tickets are still mainstream.
