@gruber An iPhone can transfer video over Wi-Fi at vastly higher rates than USB 2? Or am I missing something about that—Files or...?
@glennf Not that much faster.
@gruber Damn, Daniel, am I going to have to test this now? Or wait for USB-C. BTW, the anger and frustration over USB-C seems to have settled—I no longer get the same volume of email about it or read the same frustration in bulk online. The reason? Cheaper cables and more of them. People were particularly angry when it was both *confusing* and *expensive*. Also, OWC has a quite affordable Thunderbolt 4/USB4 cable line-up: https://eshop.macsales.com/shop/owc-thunderbolt-4-cables
OWC Thunderbolt 4, USB 4 Cables - Mac and PC Compatible

The universal Thunderbolt / USB connection cable that's compatible with Thunderbolt 4, Thunderbolt 3 and USC-C equipped Macs, PCs, and mobile devices.

@glennf Wow, good prices indeed. And that 0.3m length might be perfect for the backpack.
@gruber That issue you mention of the 480 Mbps USB speed over Thunderbolt cables…it's so maddening because there's no good way (no marking, no macOS/iOS/iPadOS alert) about the speed. Apple could have a simple interface speed presentation…which they do in Migration Assistant. Tell you what the throughput is.
@glennf @gruber A great feature for any Mac with ≥2 USB C ports would be built-in cable testing. You plug both ends of one cable to the Mac, and the OS automatically detects that, no UI needed, and pops up a dialog saying “this cable supports x mbps and x Watts power delivery”. That’s it, there is no step 3!
@sidb @glennf @gruber This sounds like a wonderful one-trick pony app for an #IndieDev #MacOS.
