Please, list the devices that you know have tb5.

Also, that's the total bandwidth in a best case scenario. You're not factoring in that you'll need to share that with all of the devices in a hub. That's without mentioning that you need the hub (which also has a cost).

    The USB4 protocol can handle 160Gb/s split asymettrically (so, say, 120Gb/s out, 40Gb/s in), wheras the upper limit for DisplayPort's highest bandwidth mode, Quad UHBR 20, is 80Gb/s in one direction. So you can saturate your DisplayPort 2.0 quad-channel with more than enough bandwidth to power three 10K 60Hz 30-bit (i.e. very high-end) monitors in DSC mode, and still only be using half the bandwidth of USB4, all using a single cable which I can also use to charge my earphones.

    Most devices only have 40gbps USB4. Which is still enough for almost all sane use cases. Frankly, if you need multiple 4K monitors get a desktop.

    Uhm no? There are more than a few use cases that require a mobile set up for demos for example but that you'd also want to use in a desk setting. For example, architects or sw dev.

    Which is still enough for almost all sane use cases.

    Like 2 4k60 monitors and literally nothing else? You have a very conservative opinion of what a "sane" use case is. Not to mention that lots of USB-C cable certification is a mess so not even getting the cable is simple (or cheap).

    Show me one architect that is actually dragging along two external 4k displays with their laptop.

    If you are a professional with specific needs buy a specific laptop. Frankly there are more than enough laptops that have more ports if that's what you need. Except even in your example you don't even need more ports because you can just use the second USB4 port.

    You misunderstood. They use those monitors when actually working in a stationary place with their desktop setup. However, it's very common to then have to go to your client's office to show them said work or discuss future steps. At which point having multiple port options comes in handy if you have to plug in to a tv, monitor or projector.

    You can't seriously consider asking for hdmi and displayport on a laptop a "specific need".

    Almost every laptop does have a dedicated HDMI port

    Why move the goalpost though? I'm not narrowing it down to a specific user in a specific setting. I'm just saying that more flexibility == more better.

    Why would you make up a specific scenario to justify getting a inferior product (from a usability standpoint) than we used to?

    That's my whole point; No, more ports isn't more better. If you don't need them they're just more cost, more holes where water/debris can get into the machine, and more wrong holes to plug the charger into. If you do need them, then buy a machine that has them - there are plenty.

    Yeah, tell me another joke. the cost is negligible. Literally from cents to a few dollars for the manufacturer.

    more holes where water/debris can get into the machine

    This literally never happened to me or anyone I know.

    more wrong holes to plug the charger into

    If you plug in your usb-c/barrel jack charger into an ethernet/hdmi/displayport input, you deserve to have a broken laptop xD

    If you do need them, then buy a machine that has them - there are plenty.

    Not really true, but ok. Keep on preaching for companies that screw over consumers :)

    K then buddy. Keep buying dongles for your dongles.

    My point is that including the ports is extremely simple. I'm not telling you that it's wrong to choose to use a dock because you find it more convenient. I'm just saying that you could have the option instead of that being the only option you have. There's no technical reason to not include the actual physical separate ports.

    Also, monitors and your earbuds? That's a very low bar. Lots of different tasks would require far more than that. Devices should be flexible.

    Agreed. It's a pity, then, that no-one has invented a single port that can replace USB-A, DisplayPort, HDMI, propriatary power connectors, Thunderb.... oh... wait...

    All high quality peripheral docks support Thunderbolt. Thunderbolt 5 docks began to release last month. You can connect the devices to the dock using USB-C, then just use one Thunderbolt cable to connect the dock to your Mac to prevent a bottleneck.

    So, barely a handful? Great. How much do they cost? And how much does it cost to just use the cable your devices come with?

    The countless remaining docks support Thunderbolt 4, which at 40 Gb/s is still twice as fast as USB-C 3.2 Gen 2x2.

    They range from $49-$299, depending on the features and number of ports needed. If you’re using the native HDMI port on your MacBook Pro, it’ll be on the low end of the price range.

    The only cable that comes with a MacBook Pro is a USB-C charging cable.

    Awesome. But what I think is ideal is having multiple ports which, in addition, would give you more bandwith, more reliability and more flexibility than a single high bandwidth hub.

    The only cable that comes with a MacBook Pro is a USB-C charging cable.

    You misread. I was referring to the cables the devices you use with your laptop come with.

    MacBook Pro comes with three Thunderbolt 5/USB-C ports (120 Gb/s), HDMI 2.1b, MagSafe 3, and a 3.5 mm headphone jack. Trading a USB-C port for USB-A means potentially downgrading a USB-C capable device to USB-A with an adapter. The opposite results in better performance, and the adapters will continue to be useful as long as you own USB-A devices. When computers only have USB-C ports, your other adapters will be useless.

    As for cables, I replace them rather than using adapters. Monoprice.com sells quality cables relatively inexpensively.

    Again, missing the point. There's nothing you need to "trade". They could simply add more ports.

    Monoprice is not a worlwide brand and buying more stuff is not a sensible solution to a manufactured problem.

    There’s nothing simple about adding more ports on a portable computer. It means additional buses, I/O boards, and a larger device size.

    Most manufacturers that offer USB-A ports don’t have three Thunderbolt 5 ports. It would either be modular or a trade if you’re making a true comparison.

    If they could do it in 2010, they can do it in 2024. And no, it wouldn't significantly increase the footprint.

    About TB5 you're right. Most laptops don't have it but you're also conveniently ignoring that the first laptops with those ports were released literally a few months ago.

    Tell me where there’s room to add another bus and ports without expanding the footprint.

    https://www.macrumors.com/2024/11/22/ifixit-shares-m4-macbook-pro-teardown/

    Thunderbolt 4 still has twice the bandwidth of the fastest USB-C standard currently available at 40 Gb/s. Thunderbolt 5 tops out at 120 Gb/s. That means you could have six USB-C devices, running max throughput of 20 Gb/s through a dock, connected to the Mac using Thunderbolt 5, without limiting the bandwidth. It also daisy chains more 4K displays at a higher refresh rate than USB-C. It’s a far superior connection.

    There is a lot of empty PCB in that design. They could at the very least add 1 more port on each side if they wanted to. The audio solution is also taking up quite a bit of space.

    Agai with the TB5. Those hubs cost $200+ and some even require external power. It's a good option to have. It's bad if it's your only option.

    Empty PCB? You can’t see the other side of the logic board in this video. All reputable computer manufacturers use circus design on PCBs.

    The cost of the dock is high because the tech is new. I don’t believe I need to explain the cost curve of advancing technology to you.
