Boox Tab Ultra
Looks pretty nice device! Even the camera makes a bit sense in the demo they give (though apparently in practice the scanning rarely works). And cheaper to boot as well. I might consider getting this one.
But is the display really better quality? Atleast the DPI is slightly higher at 219 on the Boox Tab Ultra vs 190 on the Daylight. And Boox weighs 70 grams less, and that’s the device some reviews call heavy (and some lightweight…).
These reviews mention the slow display speed:
So perhaps there is some room for improvement? That being said, some other reviews don’t mention it and one says it’s faster than typical e-ink display, though that doesn’t sound immediately purely praising.
In the end it probably comes to the software: how fast it is, it well it works, how nice it is to use. It seems both have customized the standard Android, so I suppose the difference is in which one has done it better and which one has better custom apps. Per the reviews Boox doesn’t fare too well in this aspect. Maybe someone will make a comparative review of the devices.
It still loses to HgBa2Ca2Cu3O8+6 with Tc = 133–138 K at normal air pressure, though. (I assume it’s normal air presure as the article doesn’t say the pressure for it, while it refers to some others as high-pressure ones.)
Maybe LK-99 still has other benefits, such as not using mercury.
Alas my game PC is going to stick with Windows due to bad state of VR in Linux :/. And therefore one day it might need to update to Windows 11.
In particular if you have a headset that is not Valve Index, though apparently with Meta Quest one can use ALVR, as long as you get the actual games running.
