This looks like an attractive product and (currently) at a reasonable price point to!
Have a laptop or other device with a low-end iGPU or low-mid range dGPU?
While you'll be stuck with the above when on the go or out in the wild, however with this device you can 'dock' to a boost of GPU power *IF* you at least have a USB4 or Oculink port!
IDK how much (if any) "docking stations" have caught on for home users/consumers but many professionals use them in the office.
This is a great start, the OneXGPU is ridiculously overpriced for a 7600xt mobile GPU. This one is a little more down to earth. For contrast, for $750 you can put together an eGPU that can do either Oculink or USB 4/Thunderbolt (but not both) with a 7900GRE. It won't be as portable, but for the intended use, I don't really care about it being super portable, the Radeon 780m iGPU that is in most current Oculink devices is still capable of gaming in a pinch one on the road.
I don't really see a use case for gaming on the road with an external monitor, if I'm not at home I am going to want to play on the monitor built into my device and if I'm at home I don't really care if my eGPU is the size of a Razor Core X and doesn't fit in a laptop bag.
I still think these need to come down to around $300 to catch on at this performance level. Also, you can buy a laptop with a 4060 or even a 4070 built in for less dough than one of these plus a laptop.

Gaming in hotels or temporary residences that provide a large screen TV?
Portable egpus are admittedly quite a niche use case. I take a mix of short and longer trips abroad quite frequently. For the short trips, I would love a portable egpu solution as I usually leave the laptop behind and just pack my Legion Go and an ipad mini. But at current pricing, I'm not tempted, they would need to come down significantly. I have an empty Aorus gaming box, and for €400, I can put a Palit 4060ti in there which is significantly better than 7600M XT. But of course it isn't quite as portable...
