This is exactly the usecase I imagned, which stopped me from buying a Surface Pro.
I think upgradability is also a very interesting point. You don’t have to upgrade two devices.
Let’s say I buy the eve V and a eGPU. 2500$ total.
If in 3-6 years my GPU is too slow, I just buy a new GPU, if my Laptop is to slow, I buy the next version of Eve V.
With the usual setup of Desktop and Laptop if the GPU is too slow, I can just buy a new GPU, but as soon as the CPU is too slow, I have to buy both, new Desktop CPU and a new Laptop. Worscase, my desktop CPU socket is not supported anymore and I would have to buy a whole new computer.
The only Problem I see, is an upgrade to Thunderbolt or the cable, which won’t let me use my old Laptop oder eGPU. But since the eGPU is cheaper than a whole computer, it doesn’t hurt as much.
