Indeed! A Waveshare portable e-ink monitor is $499.99 for the 10.3" size, almost identical to the Daylight's 10.5" display. The external display would also outlast this tablet device for sure.

And if I'm reading the MediaTek Helio G99 specs correctly, it seems to have similar raw performance to a Raspberry Pi 5. One could easily put together a little "productivity PC" using a Pi (or a Windows mini PC), a power bank, and have the added benefit of full-fledged desktop apps rather than Android versions of them.

I wanted to want to impulse buy this thing. But the above analysis, as well as the lack of any real hands-on 3rd party video-based reviews will be a no from me.
