smallest wired keyboard?

It has three advantages over Bluetooth. First, it uses less power so you won't be recharging the keyboard very often. Second, there is no pairing necessary, it's all automatic. Third, it works with just about any device with a USB port, including Android phones. Fourth, the connection doesn't ever drop. The disadvantage of 2.4GHz is that it requires a separate receiver, though sometimes, depending on the device, so does Bluetooth. For example, I use a 2.4GHz wireless keyboard with my smart TV which is a lot easier than trying to enter credentials or search criteria with the TV remote. The TV has no Bluetooth but it doe shave a USB port.

But yes, there is the hassle of charging the batteries on wireless devices. Fortunately, a keyboard is not like a Bluetooth speaker or Bluetooth headphones, it uses very little power so recharging it isn't required very often. Also, you could just leave in plugged into the USB port all the time, constantly charging, so you're no worse off than with a wired keyboard.

In 2016, Tim Cook did display a prototype of an iPhone that was much more fully featured in terms of interfaces, but alas, no parallel port. See

that is false. bluetooth uses *less* power, with some bluetooth keyboards and mice having as much as two years on a single charge.

modern bluetooth peripherals do not need pairing, and for those that do, it's a trivial one-time step. hardly an advantage.

that may be true, but just about everything has bluetooth so that's not an advantage either.

you said three advantages (not that any of what you listed is an advantage).

nor does bluetooth.

although, if you move far enough away, any connection will drop.

that is a significant disadvantage, especially for a mobile device such as a phone or tablet.

a dongle also uses up a usb port, eliminating the advantage of going wireless.

another disadvantage is only one dongle can be used, thereby limiting it to only one device. a second dongle will cause all sorts of problems.

some bluetooth keyboards support multiple pairings and can work with multiple devices, often automatically switching between them, which is another *huge* advantage of bluetooth.

The parallel port is also super easy to use. Even in the early days you could use the four control lines as inputs so it was bi-directional, 4 bits at a time, but as it evolved it became fully bi-directional with a direction control bit (which caused problems for some users who would inadvertently set the bit to input).

no they didn't.

the new macbooks have usb-c/thunderbolt ports. there are no usb-a ports:

that's because macbooks are nowhere near as space-constrained as a phone as well as used in very different ways, with very different needs.

That is an urban legend. That is not possible. Even if not used these devices have perhaps only a minimal residual energy.

it's reality.

here are two:

Battery: 2 x AAA Battery: 24 months

there are also bluetooth devices that use coin batteries which last for a year or more.

if it's not used, it will last even longer.

lithium aa/aaa batteries have a ~10 year shelf life.

No.

And we discuss accumulators not ordinary one-way batteries which are environmental killing waste from day one and not acceptable anymore.

But even these batteries are considerably drained after a year.

In addition: These performance claims by the manufacturers are never cross checked by anybody and are *always* unrealistic.

My rechargeable Apple-mouse was said to last 3 month with a full charge. No way! With my usage profile I can be happy if it lasts 3 weeks. The completely unacceptable environmental profile of the battery driven mouse was the reason why I exchanged it for one with an accumulator. 3 weeks max.

No, they buy them because they feel safe with them and convince themselves that what they do is what they really wanted to do

I have never called the help line for a knife and fork

yes.

there are several such models. i linked two. there are others.

it doesn't matter what type of battery it uses.

not always. it depends on the battery and usage.

actually, they're reasonably accurate.

but if it turns out to be 1.5 years instead of 2 years, very few will complain.

the fact is that battery life for modern bluetooth devices is not an issue whatsoever.

You can still buy a PCI card with a parallel port. Old laptops are a different story. Some had a parallel port, others had a CardBus or ExpressCard slot and could use a parallel port card. USB parallel port card adapters are not going to be useful for real-time control.

Riiiiiiiiight.

Everyone in the world who disagrees with you is an easily swayed sheep!

Apple's products have exceptional loyalty. People buy them, and then buy another and another.

The reasonable conclusion is that they do so because they are satisfied with them; even happy with them.

Which is relevant...

...how, exactly?

Is that all consumers...

...except you?

You're clever enough to see through it, right?

:-)

Apple didn't delete the 3.5mm (1/8") stereo headphone jack to sell knew stuff.

They did it because a deep jack like that makes for a mechanism for damaging the phone if it gets levered.

It's also more difficult to achieve acceptable levels of water resistance with more openings in the phone; particularly an older port design never designed with water resistance in mind.

The Lightning port was designed for water resistance.

Solved for $9.

Showing your open-minded nature!

What is a "rapi"

Which can be connected with the same adapter...

raspberry pi, one of the two groups to which this is cross-posted, for reasons known only to 'arlen'.

note that the raspberry pi zero (all varieties) does *not* have a 3,5mm jack.

No quite the oppsite. Given a certain torque (determined by the outside), the forces damaging stuff inside are smaller the longer the lever is and vice versa.

What specific parts of the "mentality & ethos" do you find objectionable?

he's correct. torquing it *will* damage the phone, usually with part of the plug stuck inside, requiring service to remove the plug and repair any additional damage.

You think Apple is making any significant additional revenue from the deletion of the headphone jack?

Please.
