They could fit 4 USB-C, or 6 MicroSD, or 12 headphone jacks! But none of that really matters. The elegance of the original model is that you get 4x Thunderbolt 4-capable ports that can run at full-speed and easily interface with any standard USB device. Sure you could add more ports, but you're just diluting the speed of the interface and adding more steps between your device and the laptop's IO controller. > the fact that nobody has made one in the year this product has been out makes me wary Did you look? https://community.frame.work/t/dual-usb-c-expansion-card-moc... Same problems exist as-usual when you try multiplexing Thunderbolt connections, Alt-mode and PD gets really funky. |

I did look. Did you? That thread is a year of people speculating about if this would even be possible and a few prototype renderings. There is no evidence in that thread that anyone has even created a physical prototype, much less an actual working adapter.

I don't want elegance. I want sustainability, repairability, linux compatibility, and more than four ports.
Edit: I would have much preferred if they had maybe 1 or 2 TB4 expansion slots, then take those other 40Gbit/sec TB4 pci-e lanes and have a bunch of standard ports that are easily replaceable on the motherboard, which all together wouldn't even come close to saturating a single TB4 lane. Add up 3x USB-A/C 3.2 Gen 2 (10 Gbps each, or 5Gbps for USB 3.2 Gen 1), 2.5Gbps ethernet, 100Mbps SD card, and you're still well under the bandwidth for one of the 4 lanes. Then have the other pci-e lane do HDMI 2.0b.

I (and likely most people) don't need 4 TB4 lanes at 40Gbps each. The ethernet expansion card that sticks out of the case is max 2.5Gbps. Where is the rest of that bandwidth going?
