Its approximately price competitive to purchasing a small monitor with speakers... but its much more portable. I presume one can shop around and find it cheaper than the link I've posted - I only looked about for a few minutes as its been quite a while since I'd shopped for this when I researched it the first time around.

I'm not sure an HDMI input capable notebook exists. If it did, given the variety of factors involved in what I want in a notebook, its almost certain that I would have issues with certain aspects of its design (keyboard? mouse? screen? battery? physical size? cost of components? port counts? overall carry weight? etc.)

Using an external capture device frees one from that "locked into a notebook I kind of don't otherwise want" decision. As well, since it is external, it can be used among multiple computers - each subsequent laptop can be whatever laptop you want and have the capability of hdmi input.

A secondary use - the usb hdmi input can be used to stream (twitch...) gameplay from another source (retropie, NES classic, ps4, etc.)
