The work required to build an actual secure, maintainable product on top of an SBC is so big that you'd surely never use one of these. The hard work is all in software. You need a supplier with product lifetime guarantees and a known SoC manufacturer.
If you're a hobbyist, unless you really don't value your time you'd be much better served buying an x86 PC or a Raspberry Pi for whatever project you've got. Any money saved buying one of these would be completely negated by the extra time taken to maintain it.
So who's the target market? Are there products out there built on these? Or are they mostly just shipped straight into desk drawers? How many of these do they actually ship?
I've only ever had phones with at least one (regular/physical) eSIM, and a 'slot' for an eSIM for travel.
What are the pros/cons of only eSIMs?
Edit: I'm not questioning eSIMs, which I know can be handy: my iPhone SE3 is physical+eSIM. I'm curious about no physical SIM. If you can support 1-eSIM+physical is it a big deal to go to >1-eSIM+physical?
For a week I've been using KeePassXC + Syncthing between four devices. Syncthing is also syncing my Obsidian vaults which has replaced Apple-only Notes.app.
Bitwarden is definitely more polished, and Syncthing is definitely (much) more fiddly than using Bitwarden's and Obsidian's ($5/mo) native syncing tools.
But I like the idea of having the same syncing solution across all apps on all devices. Curious if anybody can recommend this setup or if collisions will make it unbearable.
