The Astro Slide definitely does look interesting and I’d not seen this one before. I also wasn’t aware that you couldn’t get the Fairphone in the US, which is a shame.
I’m having to do some considered calculations on shipping and imports for something I desperately want that has to come from the US and it’s a pretty big barrier to being able to afford things. Hopefully this is something which will change as more and more people become enthusiastic about modular tech.
