For projects, yes… most of the things I want to build don’t need to go fast, so the pi zero is amazing and so so small. If you are just talking little cheap computer to stash somewhere, then no. I do think it would be neat if someone made a SBC N100 in the “credit card” size.
I’m not saying that they won’t do this, but so far their actual actions have ended up pretty decent. I’ve had 3 Synology devices over the last 12(?) years, and while they are not perfect, they have been very good at delivering what they promised over the long haul. All of them still work fine. Even the old guy delivers.
