Be aware that planetcomputers/astro slide has done a really really bad job of supporting their devices with os updates on the Android side.

Even with some linux support (which I haven't checked lately) it was a hard pass to support the slide.

When I first saw their Indiegogo advertising that it could boot Linux, I tried looking for any pictures/video/evidence of it, and found nothing.

It does "run", but it's not really running Linux. It's just android with a halium layer running Linux software on top. So when android support ends, which it will seeing how they've not been great at software support, your "Linux" build will also no longer get updates. That's why Mainline Linux is such a big deal, as even if support ends, you'll still be able to get the latest Linux kernel and distributions can continue basically forever supporting the device.
