Android handsets aren't really linux boxes. I can't ssh into them, I can't write little python scripts, etc. An actual, general purpose, real foss portable phone factor computer will be amazing as it matures.
There's nothing new here. I remember having those features in the Nokia N900 in 09. I think this product is grossly overpriced for a cheap generic Android phone loaded with a beta Linux distro. In Shenzhen they'll sell you a case of 50 for $400. Save your money or buy a Quest 2.
It took Google tens of thousands of paid top tier developer hours to make Android useable. I'm betting never. In a year or two there's going to be some nasty passive aggressive apology blaming the woes of the world for why it couldn't happen and these guys will go home with their big sack of money. Seriously you want a shit Android ARM phone loaded with a beta Linux distro? Let's order a lot from Shenzhen and everyone can pay the $50 it's worth.
Just a linux computer with a cellular modem sounds amazing to me, tbh.
