The MacBook Neo runs an A18 Pro phone chip. It's appears to be all there and somewhat ready to give us something like DeX [1].

Something like DeX is already lying dormant on iOS and it's already enabled on iPadOS.

But, if you modify the MobileGestalt plist on the iPhone, you can enable the "Stage Manager" desktop mode and connect a mouse, keyboard, and monitor and you get a desktop from your iPhone.

Caveat: due to artificial reasons, it's not really usable for daily driving due to the way the hacks work, but Apple could certainly make some trivial changes and get it going.

yes, and the fact that it runs a phone chip is the reason why it only has one 10Gbps USB-C port and the other only supports USB 2.0 speeds...

10Gbps is 12 times slower than the maximum bw of TB5.

You could argue most people wont need that speed, but most people don't need pro phone too.

Yes, and TB5 also uses around 10x as much power, around 4W rather than 0.4W for USB3, which would consume the majority of the sustained power budget of the entire phone.

Something else will drop the ball guaranteed.

Can you show me the workflow which uses this and has an iPhone as the bottleneck

Moving my videos from ip to my TB ssd ?

are these videos larger than the iphone SSD or TB SSD DRAM buffer and will need to drop to NAND erase/write speed?

No, but i dont understand your point ?

The point is, with your example the link speed of the iPhone isn't the limiting thing of your example. You'll likely be limited by the speed of your storage before you saturate that link.
